岩层组合特征对近直立煤岩互层巷道失稳的影响
Influence of strata combination characteristics on roadway instability in near-vertical coal-rock interbedded formations
摘要
Abstract
Aiming at the problem of asymmetric deformation and instability in the mining process of nearly vertical coal-rock interbedded roadway,this study took Wudong Coal Mine in Xinjiang as an example,constructed a mechanical model of roadway surrounding rock partition to analyze the influence of different coal-rock combination characteristics on roadway stability.The results show that the surrounding rock after roadway excavation can be divided into six areas.Areas I and Ⅳ are relatively stable,areas Ⅱ,Ⅲ,Ⅴ and Ⅵ are easily damaged,and the whole is dominated by shear failure.The distribution of soft rock aggravates asymmetric deformation and lateral shear failure.The combination characteristics of rock strata and stress coupling are the root causes of roadway instability.A combined differential support scheme of"bolt(cable)+steel strip+metal mesh+shotcrete+roof anchor cable strengthening support"was proposed,which effectively curbed the deformation of surrounding rock and greatly improved the stability of roadway.The research conclusions provide a theoretical basis for the stability evaluation and disaster prevention of near-vertical coal-rock interbedded roadway.关键词
