Introduction

With the deepening of coal mining in the east of my country, the development and utilization of coal resources in the west, the advancement of mining technology and the changes in mining methods The hydrogeological conditions of coal mines have become more complex and diverse. At the same time, the exploration technology has also improved. In order to standardize the hydrogeological exploration of coal mines, This standard is specially formulated for the quality of coal mine hydrogeological survey results to meet the needs of coal mine water prevention and control work. This standard is based on Earth System Science And groundwater system theory and methods, combined with decades of coal mine water prevention and hydrogeological exploration work experience results based on the formulation. Specifications for special hydrogeological surveys for coal mines

1 Scope

This standard specifies the general principles of special hydrogeological surveys, survey methods and technologies, mine hydrogeological surveys, special hydrogeological surveys, Basic requirements for hydrogeological survey of open-pit coal mines, hydrogeological survey of closed pit coal mines, design documents and reports. This standard is applicable to the hydrogeological survey in the whole process of coal mine design, construction, production, and pit closure.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Specialhydrogeological explorationincoalmines In order to ascertain the hydrogeological conditions of coal mines, hydrogeological work using comprehensive methods such as hydrogeological surveying and mapping, geophysical prospecting, drilling, and testing. Note. According to coal mining method and purpose tasks, it can be divided into mine hydrogeological survey, special hydrogeological survey, open pit coal mine hydrogeological survey, closed pit coal Mineral hydrogeological survey. 3.1.1 Minehydrogeological exploration In order to find out the water filling conditions of the mine, comprehensive methods such as hydrogeological surveying and mapping, geophysical prospecting, drilling, and testing are used to predict and evaluate the water inflow in the mine. Hydrogeological work with the risk of water inrush. 3.1.2 Open-pitcoalmine hydrogeological exploration In order to ascertain the hydrogeological conditions of open-pit coal mines, comprehensive methods such as hydrogeological surveying and mapping, geophysical prospecting, drilling and testing are used to predict mine drainage Hydrogeological work of water volume. 3.2 Water-filing aquifer The mine tunnel project or the open pit exposes the aquifer that fills the mine with water within the affected area. 3.2.1 Main water-filing aquifer Under the mining conditions of the ore deposit, one or more aquifers with a large water-filled capacity are generated in the shaft. ......
