Technical Research on Drilling Technics of Comb Directional Drilling on Floor of Complex Strata in Coal Mine
Taking the project of Fa'er Coal Mine of Guizhou as the research object,the basic situation of the coal mine project was briefly introduced,and then the drilling process of comb directional drilling was analyzed,and the application effect of the process was verified.Through the verification,it can be seen that the application of the process can improve the efficiency of gas extraction,help reduce the cost of gas treatment,and can be popularized on a large scale.
