Mining pressure relief boundary detection method

Abstract

The invention provides a mining pressure relief boundary detection method. According to the method, a transient electromagnetic method, a seismic exploration method, a numerical simulation method and a high-density electrical method are utilized in a mining stable area to obtain corresponding mining pressure relief boundaries from different parameter angles, the data of the obtained mining pressure relief boundaries are optimized in combination with the actual condition of a stope, the accuracy of determining the boundaries by all the methods is improved, and the method is suitable for popularization and application. All the mining pressure relief boundaries after data optimization are fitted, and finally the mining pressure relief boundaries are obtained. According to the method, the complexity and variability of the geological structure are considered, the determination accuracy of the mining pressure relief boundary is improved, and the mining pressure relief boundary can be accurately obtained. The method is of great significance in eliminating coal and gas outburst danger, and provides powerful guarantee for safe mining of coal mines.

Description

technical field [0001] The invention relates to the field of mine engineering, in particular to a method for detecting the pressure relief boundary of mining. Background technique [0002] The existing mining pressure relief boundary detection method has low reliability, coupled with the complex geological structure, it is impossible to accurately deduce the real pressure relief boundary, which in turn leads to inaccurate judgment of the location of coal and gas outbursts, and ultimately leads to safety accidents and economic losses. At the same time, there will be large errors in detecting the pressure relief boundary of mining with a single detection method. Therefore, it is of great practical significance to establish a method suitable for mining pressure relief boundary detection. Contents of the invention [0003] The purpose of the present invention is to provide a mining pressure relief boundary detection method to solve the problems in the prior art. [0004] The...
