A GIS-BASED METHODOLOGY FOR GREEN ROOF DESIGN IN A DENSELY BUILT-UP AREA IN ULAANBAATAR, MONGOLIA
(GMIT, 2022) Nandin-Erdene Saranbaatar; Uuganbaatar Zulkhuu; Gantuya Ganbat
Ulaanbaatar has the highest population density in Mongolia. Consequently, for the past few decades, the massive movement of people to the city led to unplanned urbanization. Today, Ulaanbaatar is facing environmental problems in all seasons of the year. To resolve these issues, some measures have begun such as the “Green City Action Plan for the City of Ulaanbaatar”, and “Green building guidelines”, not to mention “A Billion Tree National Campaign”.

ADOPTION OF THE TOWARD SUSTAINABLE MINING (TSM) STANDARD IN MONGOLIA: RECOMMENDATION BASED ON THE EXPERIENCE OF THE ‘ENERGY RESOURCES’ LLC
(GMIT, 2025-06-04) Oyungerel Ganbaatar; Supervisor 1. Prof.Dr. Enkhzaya Ch.; Supervisor 2. Mrs. Batbayasakh A.
Energy Resource’ LLC is used as a case study in this thesis to examine the adoption of the Towards Sustainable Mining (TSM) standard in Mongolia and evaluate the opportunities and difficulties of applying global sustainability frameworks to the mining industry in Mongolia. This study investigates awareness levels, operational gaps, and institutional readiness for sustainable mining practices through semi-structured interviews and structured surveys with ‘Energy Resource’ LLC employees at the Ukhaa Khudag Mine. Survey results reveal that while 70% of regular employees were unfamiliar with the TSM standard by name, most actively supported sustainability principles in their daily work. Significant difficulties with training, documentation, communication, and resource allocation were found through thematic analysis of interviews. The main challenges were poor comprehension of the TSM criteria, a lack of organized training, inconsistent language, and restricted access to historical data. The study employs a weighted challenge evaluation system and proposes practical recommendations such as mandatory TSM training, centralized document management systems, standardized terminology, and dedicated TSM implementation teams. The findings underscore that companies with existing ISO certifications were better prepared for TSM adoption, highlighting the value of integrated management systems. Ultimately, this thesis provides policymakers and mining companies in Mongolia with practical advice on conforming to global sustainability standards. It concludes that Mongolia can establish its status as a regional leader in responsible mining by strategically investing in internal capacity and stakeholder engagement.

Total of 9 CCBs and 1 electric-arc furnace slag from 7 different location/plant have been evaluated to represent Mongolian CCBs. Backfill mix designs were designed to compare the materials and to choose the best suited material for backfilling purpose.
APPLICATION OF SEED ZONE MAPPING IN MONGOLIA: A CASE STUDY FOR MINE REHABILITATION;
(GMIT, 2026-06-20) Nomin-Erdene G.; 1 st Supervisor: Prof. Dr. Gantuya Ganbat; 2 nd Supervisor: Prof. Dr. Yong Ho Lee
Land degradation from mining activities represents a critical environmental challenge in Mongolia, where the lack of a systematic framework for native plant material selection has limited the effectiveness of mine rehabilitation. This study addresses this gap by developing the first comprehensive GIS-based seed zone map for Mongolia, delineating 44 discrete seed zones through the integration of natural vegetation zones, plant hardiness zones derived from January minimum temperature, and precipitation zones derived from long-term annual precipitation data. The delineation followed a hierarchical, ecoregion-first approach implemented in ArcMap 10.8, with statistical validation performed using PERMANOVA, pairwise environmental distance matrix analysis, and Linear Discriminant Analysis (LDA). PERMANOVA results confirmed statistically significant environmental differentiation among the six ecoregion groups (F = 4.808, R² = 0.388, p = 0.001), with LDA accounting for 72.8% of between-group variation along the first discriminant axis. The framework was applied to the Energy Resource LLC (Ukhaa Khudag coal mine) in Umnugovi province as a case study. The mine was identified within seed zone MZ7 (Dundgovi Desert zone, H5, Semi-dry), and evaluation of current practices revealed that distant seed sourcing introduces a measurable risk of maladaptation. Native species such as Haloxylon ammodendron and Caragana spp. were identified as the most ecologically suitable for MZ7 conditions. The developed framework provides a scientifically grounded spatial decision-support tool for guiding seed sourcing in mine rehabilitation and ecological restoration across Mongolia.

Assessment and Modernization of Relay Protection Systems for Auxiliary Transformers at Thermal Power Plant No. 4: Bachelor Thesis
(GMIT, Nalaikh, 2026-06-20) Namuun Ts.; Ankhbayar V. Thesis Supervisor 1st; Ariunbolor P. Ph.D, Thesis Supervisor 2nd
This thesis presents an engineering assessment and modernization proposal for the relay protection system of auxiliary transformer 2BT at Thermal Power Plant No. 4 in Mongolia. The reliable operation of the auxiliary power supply system is essential for maintaining the continuous and safe operation of major plant auxiliaries, including boiler feed pumps, draft fans, circulating pumps, and other motor-driven equipment required for unit operation. The study evaluates the technical condition of the existing 25 MVA, 10.5/6.3/6.3 kV auxiliary transformer 2BT and its associated relay protection system. The assessment includes connected load analysis, transformer loading verification, short-circuit current calculation, review of the existing protection functions, selection of a suitable replacement transformer, and calculation of relay protection settings for the proposed modernization scheme. The load calculation was performed using the demand-factor method, while the short-circuit current calculation was carried out using the per-unit method. The calculated apparent load of transformer 2BT is 26.25 MVA, which exceeds the rated capacity of the existing 25 MVA transformer. This indicates insufficient loading reserve under the considered operating condition and justifies the replacement of the existing unit with a higher-rated transformer. Based on technical compatibility and capacity requirements, the ТРДНС-32000/10 У1 transformer with a rated power of 32 MVA is selected as the preferred replacement option. The calculated three-phase short-circuit currents are 26.07 kA at the 10.5 kV side and 15.08 kA at the 6.3 kV auxiliary bus section. The existing electromechanical relay protection devices are technologically outdated because they offer limited setting flexibility, lack self-diagnostics, lack disturbance recording, and have restricted communication capability. Therefore, the SEL-387A microprocessor-based transformer protection relay is proposed for modernization. This relay provides three-winding differential protection, backup overcurrent protection, harmonic restraint, thermal overload protection, breaker failure protection, event recording, and communication functions. The economic evaluation shows an estimated annual saving of 33,000,000 MNT and a payback period of approximately 9.4 years. The results demonstrate that the proposed transformer replacement and relay protection modernization will improve the reliability, selectivity, sensitivity, and maintainability of the auxiliary power supply system at TPP-4.

ASSESSMENT OF CLIMATE AND VEGETATION CHANGES IN SOME AREAS OF THE MONGOLIAN PLATEAU USING SATELLITE DATA
(GMIT, 2025) URANGOO Baasandorj; 1 st Supervisor: Prof. Ph.D. Gantuya Ganbat; 2 nd Supervisor: MSc. Nandin-Erdene Geserbaatar
The Mongolian Plateau is one of Central Asia's most climatically sensitive regions, where ecological changes driven by temperature rise, precipitation variability, and land-use pressure pose growing challenges for environmental sustainability. This study investigates long-term changes in vegetation and climate across three representative plateau regions, including the southern desert, the eastern steppe, and the northern forest-steppe, using satellite-derived data from MODIS sensors (NDVI, LST, and ET) from 2000 to 2024. Data processing and analysis were conducted using Google Earth Engine and QGIS, applying normalization, standardization (Z-score), and weighted integration through the Analytic Hierarchy Process (AHP). A regional vegetation–climate response type classification was developed, dividing each study area into four types based on environmental conditions and interannual variability. Which are: ● Type I: high NDVI, low LST and ET, with low changes ● Type II: low NDVI, high LST and ET, with low changes ● Type III: high NDVI, low LST and ET, with great changes ● Type IV: low NDVI, high LST and ET, with great changes In Umnugovi Province and neighboring areas of Inner Mongolia, Type I and Type IV accounted for 18.9% and 37.4% of the total area, respectively. In eastern Mongolia (Dornod and adjacent settlements), Type I and Type IV covered 28.8% and 34.0%, respectively. The northern regions (Selenge and Darkhan) exhibited smaller proportions of these types, with 5.0% for Type I and 19.3% for Type IV. These classifications highlight the spatial heterogeneity in vegetation-climate responses under changing climatic conditions and emphasize the value of remote sensing data in informing regional environmental management, land-use policy, and climate adaptation strategies, particularly in mining-affected landscapes

(GMIT, 2022) Bolorchimeg Turkhuu; Ariuntuya Tserendor; Byambakhuu Ishgaldan
The Tuul river basin is a unique region in that it covers only 3.2% of Mongolian territory, but 48% of Mongolian total population lives in Ulaanbaatar. Also, 66.5% of the Mongolian total GDP was produced within this river basin in 2020. Land-use changes due to the expansion of urbanization can pose a threat to downstream ecosystems of the Tuul river, particularly soil and water quality, leading to an increase in surface runoff and nutrient loads.
Assessment of Potential Material Reprocessing of Erdenet Mine Tailings
(GMIT, 2020) Azjargal Sengedor; Munkhjargal Chimeddorj; Battsengel Baatar
The objective of this study is to define possible ways to reprocessing Erdenet mine tailings with potential metal recovery. These tailings have relatively high copper and molybdenum concentration (e.g. tailings III has Cu: 0.2-0.5%, Mo: 0.1-0.2% content), some of which are concerned as reusable deposits. But the measured concentration of metals does not have a homogeneous population over the whole tailings due to settling of the materials, reclamation of process water and drying of the materials, etc. The tailing facility is one of the largest in the world with a total area of 18.6 km2. Over 40 years of history of Erdenet processing plant, the tailing has been collected in the tailing dam and now becomes the biggest resource for research

Autonomous inspection and data Gathering Robot
(GMIT, 2025-06-04) Soronzonbold Munkhzul
In the modern era, the robotics field is advancing rapidly, with many human labor tasks increasingly being handled by autonomous machines. For robots—especially those operating in dynamic or unknown environments—to function effectively, they must be capable of detecting and analyzing their surroundings. This project focuses on the design and development of an autonomous inspection robot capable of environmental recognition and mapping with minimal human intervention. Using a combination of electronics and software knowledge gained both academically and independently, the robot integrates sensors, actuators, and ROS2 to perform 2D SLAM (Simultaneous Localization and Mapping). It operates within indoor environments, building maps, and navigates autonomously. Although this project is currently limited to indoor use, it lays the foundation for future development toward more complex environments, such as underground inspection. This thesis demonstrates the practical application of mechatronics skills and contributes to the growing field of intelligent autonomous systems
