The research status and view of the mining subsidence and it's control technology in china

It is a problem faced at present or about to mine the deep coal seam in china. the same time, there is question for discussing to study the mining technology concerted with environment and the method of excavating the coal under the water、the rail way、the building (coal-UBRB) this paper discussed the present actuality of mining subsidence、the means to control overlying rock and the theory research of subsidence. As a result, it can draw the conclusion that the subsidence is distributing abroad and results in the severity influence, and it also has the aspects which wait to be improved and be out of line of the mining means and theory to control the strata moving. The thesis points out that there are three important aspects which will be studied along with the development of mining subsidence subject, which are to mining the coal-UBRB completely、to simulating the moving rule of overlying rock classified、to researching the means and program with it to calculating surface distortion when using the full-mining technology. Finally, the paper views the new mining technology or means which are harmonious with the development of china mining industry.
