Study on Factors Influencing Stability of Surface Extraction Borehole above the Goaf

Article Preview

Abstract:

The paper is based on surface gas extraction technology from boreholes in the goaf in Zhangbei Coal Mine ,Huainan Mining Group .With the method of numerical simulation ,the authors have made analysis on the space-time cracking and moving law about the overburden of mining field during exploiting by contrasting extraction data about boreholes in Huainan Mining Group .Besides ,paper provides conclusion and advices on promoting the stability of borehole in the end .To some extent ,the paper is of instructive significance for the research ,promotion and application of gas extraction technology from the goaf .
