Study On Strip Mining Methods "Under-three-objects" In Yinhe Coal Mine

Yulin Yinhe Coal Mining field with numbers, complex types and distribution of a widerange protectors has serious impacted on the sustainable development of Yinhe Coal Mining,which has become a major problem to be solved by the Yinhe coal mine.Paper aim for groundprotection of buildings type and Yinhe coal seam buried in shallow thin bedrock loosethickness, the characteristics of mined seam thickness, to study such conditions strip miningof surface movement and deformation, optimize the strip mining programhas importantsignificance for the sustainable development of mining area "Under-Three-Objects" miningrealize mine.In this paper, based on the analysis of the Yinhe coal mine geology, mining conditions,protection of objects on the ground, and mine existing production technology, equipmentcondition, the surface movement observation stations were established in the first mining areaof strip mining surface movement observation; through observational dataanalysis, andnumerical simulation, experiments and theoretical analysis of similar material, compared tothe original strip mining plan further studies to optimize the Yinhe coal strip miningparameters; application of coal pillar strength theory and probability integral basin is expectedto analog method, analysis of the optimization parametersthe safety and reliability of theprogram to determine the strip mining for Yinhe coal mining geological conditions.Theresearch results show that the optimization of strip mining strip mining parameters, as well asfuture Yushen mine" Under-Three-Objects " to provide a scientific basis for mining andleaving in protection pillar.
