摘    要:煤层开采造成的覆岩破坏范围和高度是水体下采煤留设防水煤岩柱和老采空区基岩稳定性评价的重要依据,本文以岩体工程地质力学为理论依据,对覆岩破坏机理和判据等进行了研究,详细分析了覆岩工程地质类型及其组合、岩体结构特征、地层倾角、地质构造、地应力、地下水及开采条件对覆岩破坏高度及发育规律的影响。文中提出了覆岩破坏预测的工程地质学方法,并给出了应用实例。

关 键 词:覆岩破坏  采动应力场  岩体结构  防水煤岩柱  工程地质预测

Abstract:The extent and height of coal minigumduced overburden failure are significant basis for designing waterproofing coal/rock pillars of mining under water bodies and for the stability evalution of overburden above mining-out zone.Based on the theory of engineering geomechanics for rockmass,the failure mechanism and criteria of overburden are studied in this paper.Various factors such as engineering geological types and their composition,structure characteristics of rockmass,dip angle of strata,geological structure,ground stress and underground water,affecting on the height and regularities of developing overburden failure are analyzed in some detail.An engineering geological prediction method is presented and application cases are described.
Keywords:Mining induced overburden failure  Mining stress field  Rockmass structure  Waterproofing coal/rock pillars  Engineering geological prediction
