Coal mine underground water prevention and control early warning system and method and application

Abstract

The invention belongs to the technical field of coal mine early warning, and discloses a coal mine underground water prevention and control early warning system and method and application, and the method comprises the following steps: an advanced exploration and stope face water disaster prediction system carries out coal mine water-containing structure and water guide condition detection, and determines stope face water disaster prevention and control technical measures; the underground water dynamic monitoring system acquires and analyzes corresponding data of underground water by using the mining area hydrological dynamic monitoring system; the mine water source rapid discrimination system is based on existing mine data, adopts geophysical prospecting, drilling and geochemical prospecting methods to carry out testing, analysis and determination of mining area water chemical background characteristics, establishes a mining area water chemical database, establishes a discrimination model of water quality of different aquifers in a well field, and rapidly discriminates various water bursting sources. According to the method, mine water inrush prediction and early warning can be carried out in time, targeted water prevention and control measures can be taken in a targeted mode, and safe, economical and reasonable production of a mine and comprehensive utilization of water resources are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of coal mine early warning, and in particular relates to an early warning system, method and application for underground water prevention and control in coal mines. Background technique [0002] At present: the underground hydrogeological conditions of Yuwang Coal Mine No. 1 Well are quite different from the original geological exploration results, mainly due to the influence and control of the hydrogeological conditions of various water sources, the nature of channels, the structure of surrounding rocks containing aquifers, and space. Combination relations and other basic factors that have a significant impact on its water filling have been studied to a relatively low degree, and the results of geological exploration and downhole engineering have not been combined. In-depth and comprehensive research on the relative spatial position relationship between water sources or aquifers and mining coal seams, recha...

Problems solved by technology

[0005] The difficulty in solving the above problems and defects is as follows: With the continuous advancement of the working face, the stress state of the overlying rock will change continuously. This is a dynamic development process. The water vertical pressure is simplified as a uniform load, and the method of static load is used for processing. There are errors in the simulation results in terms of boundary effects, especially in thin bedrock conditions.

It is impossible to accurately and timely judge the condition of water-conducting fissures and water sources
