Mine Pressure Behavior And Research On Optimization Of Supporting Method In Shuiyindong Gold Mines

In the underground mining activities,lane, copper room, ore room, orebody,surrounding rock and make artificially produced a series of support of mechanicalphenomenon is mine pressure to show. On the choice of the ways of support,differentdegree to prevent and obstacles mine pressure appears evolved over time.People inorder to better understand and adjust, change and use mine pressure role butadoptof a variety of preventive measures, it produces the supporting technologycontinuously research and application, the exploration and development.Located in guizhou province within the territory of ZhenFengXian Shuiyindonggold mine, is a large scale underground gold deposits, since the2001years since thebuilding ore, as has been a second phase, of gold deposits in the depth of the mining,large area of mined-out area have affected the stability of ore bodies and mining. Due tothe first stage and the second phase of the ore body mining level only20m intervals,with great difficulty mined-out area, the original support method has exposed manyproblems, not only cause mine laneway, underground equipment damage and seriousinfluence the normal production of mine, have caused a large number of waste, eventhreatening workers working environment and personal safety, has been difficult toadapt to the needs of the development of the production. Therefore, this paper is basedon the gold mining of mercury hole specific technical condition of ground pressuremining and supporting technology optimization study appeared.Research work is in a comprehensive collection on the basis of the information, theexperiment study and the field test, and the combination of outstanding mining area ofthe main features of the development and the key problems, through the theoreticalanalysis and practical observation and experiment, the pressure and the supportingoptimization method appeared law, to explore the exploitation of gold mercury holemethod and the support process. The phenomenon of pressure damage field observation,the observation data analysis and summary of knowledge of ground pressure appear law;Through the brick masonry in field test and numerical simulation analysis, select thebest supporting method, in order to effectively control mining pressure activity, realizethe mining safety smoothly.
