摘要:
为深入研究深部近距离煤层上行开采过程中岩层应力分布、断裂破坏及下沉变形特征,根据深部煤层开采的具体工程地质条件,建立了深部近距离煤层上行开采相似材料试验模型,对上行开采中围岩应力变化、覆岩运动及裂隙演化过程进行了模拟分析。获得了下煤层和上煤层开采过程中,围岩应力分布变化特点及分区特征、岩层裂隙富集区主要分布区域及其演化规律,煤层开采过程中切眼和煤壁附近岩层断裂角的变化特征,并得到了两煤层工作面相对位置不同情况下,岩层裂隙富集区演化特点、断裂角变化及下沉变形规律。研究成果为类似条件下煤层上行开采、瓦斯抽采提供参考。
Abstract:
In order to research the rock stress distribution, fracture failure and settlement deformation characteristics during ascending mining in deep closer coal seam, according to the special engineering geologic conditions of deep coal seam mining, a similar material test model of deep closer coal seam by using ascending mining method was designed. The processes of surrounding rock stress variation, over-lying strata movement and crack evolution were analyzed. The characteristics of rock stress distribution variation and area division, the main distribution area and evolution rules of rock fissure cluster area, and the variation characteristics of cutting hole and rock breaking angle near to the coal wall during the lower and upper coal seam mining processes were obtained. Then the evolution characteristics of rock fissure cluster area and the rules of breaking angle variation and settlement deformation under the con-dition of different mining distances in two coal seams were acquired. It can provide the references for the ascending mining and gas drainage in the similar coal seam.
