Based on the mining geological condition of a practical long-wall mining panel in 9202 face,Sanhejian Mine,influence of pillar remained after mining of upper coal seam to the mining of lower coal seam was analyzed in adjacent coal seam.Stress which is higher than the sum of the support stresses caused by pillar and working face was revealed by means of 3D coupled numerical modeling,and rock burst will be broke out under the high stress situation.Reasonable location of the lower coal seam's… Expand
Research on the Underground Pressure Behavior Law of Repeated Mining Working Face under the Gob of Small Colliery
The gob of small colliery has been one of the main factors threatening the safe production of coal mine. The repeated mining working face in a certain mine is the practical engineering background inExpand
Characteristics of stress distribution in floor strata and control of roadway stability under coal pillars
Abstract Given the difficulties encountered in roadway support under coal pillars, we studied the characteristics of stress distribution and their effect on roadway stability, using theoreticalExpand
Numerical Simulation Analysis on Stability of Coal Pillar of Empty Mine Goaf in North of Shanxi Province
The analysis model of coal pillar of a empty mine goaf in north of Shanxi province was constructed and the process of coal pillar from formation to weathering was simulated through the application ofExpand
Study on the bearing structure and stability of overlying strata: an interval gob in shallow buried coal mining of Northwest China
The bearing structural characteristics of overlying strata in overlying gobs are the main factor in inducing dynamic disasters in roof in close-distance coal seam group mining. In the present work,Expand
