Forecast System Of Mining Damages In Mining Areas Based On Geology

Underground mining own75 percent in ore dimensions in China and the underground mining dominate coal mining. Underground mining own 92.5 in coal mining and 67.3 percent in all of the used mining fields. Then underground mining of coal mining is the largest kind of dimensions in ore mining. So the mining damages are the biggest one and mining owned more dimensions than other damages. Someone evaluate that our country almost lose 400,000,000 RMB each year. Aimed to produce clean and control the mining damages , title of the paper is "Forecast system of mining damages in mine areas based on geology" .In order to control the mining damages ,at first we must make the influence factors clearly. The factor of mining damages include mining factors and geologic factors. The mining factors include mining thick, mining depth, mining ways, re-mining, time and mining length. The geologic factors include the upper rocks stress characters, geologic tectonic and tectonic stress influences. Among the geologic influence factors there are faults and the angle of mines. This thesis synthesis the shortage of thinking about geologic ways of former specialists,and gather my instructor theory,from the geologic tectonic ways and tectonic stress ways think about the influence on the mining subsidence,And then quantify them . In using forecast formulas,the author apply the theory of Xia Yu-cheng of Xi ' an University of Science and Technology to the amend formula of the max of subsidence and the experienced formula of moving distance. So the author used the get data to imitate subsidence plots and in the end used the software Win Surfer to show them. The forecast system of mining damages in mine areas based on geology's main functions are : draw the research scope and get necessary data; surface subsidence plots with the mining length increase; show the picture of the surface subsidence equal-value plots. Finally the author use the example of Dong-pang mine of Xing-tai mine company to manifest the system. And the results show that the system is correct and reality.
