Optimized Analysis for Optimal Path of Surface Gas Drainage Hole

In order to drain gas in goaf effectively, some of mining area used a method of surface drainage hole. In order to improve gas drainage efficiency and ensure drilling from destruction of strata movement in mining process, we must optimize hole arrangement scheme. We analyzes overburden failure in mining process and deformation distribution of strata movement from mining subsidence, and puts forward optimal final hole regional and optimal path of gas drainage borehole. Measursd data of a certain mining area explain the rationality of optimization scheme in this paper.
