The main functions of the department include mineral exploration, geotechnical work, and mineral administration. The tasks related to mineral exploration and geotechnical studies are carried out by geologists specializing in geological sciences, while mining administration functions are handled by mining engineers specializing in mining technology.
The Minor Mineral lease is granted under UP Minor Mineral Concession Rules 1963. The lease is sanctioned by the District Magistrate of the concerned district except limestone marble and dimensional granite which is sanctioned by the state government. The application is submitted to the concerned DM office and forms are available in the UP Minor Mineral Concession Rules 1963.Under mineral exploration, geologists conduct field surveys to assess the potential availability of minerals. If preliminary studies yield promising results, rock samples are collected from the area for chemical analysis, petrological examination, and other tests. Mapping of the area is carried out to create detailed geological maps. Additionally, geophysical studies are conducted to analyze subsurface conditions.
If all these studies and tests yield satisfactory results, drilling operations are undertaken using drilling machines to determine the distribution, type, and availability of underground minerals. The quality and quantity of mineral reserves are then evaluated based on these findings.
For the regulation of mines and the development of minerals, the state government grants mineral concessions in accordance with the rules and policies enacted under the provisions of the Mines and Minerals (Development and Regulation) Act, 1957, legislated by the Central Government.
The state government earns revenue based on the quantity of minerals extracted. Before approving mineral concessions, technical consultations are conducted, and mining plans are reviewed. The extraction of minerals from approved mining lease areas is regulated under the prevailing policies and rules, ensuring environmental and ecological considerations.
Under geotechnical work, the department provides technical insights on land suitability and stability from a geological perspective for various infrastructure projects such as buildings, bridges, roads, canals, drinking water schemes, and power transmission towers. Additionally, the department studies landslide-affected areas and submits recommendations and suggestions to the government/administration for mitigation and protection measures.
