摘要
以东滩煤矿3303综放工作面在FS46断层附近的轨道顺槽为研究背景,采用数值模拟与现场观测相结合的方法,探讨了3303综放面轨道顺槽在上覆煤层开采期间的应力分布变化情况,并通过对3203工作面回采巷道变形量的分析,对应力集中区域进行分析和划定,进一步认识了构造复杂区域的矿压显现规律,揭示出复杂地质构造对煤层开采的影响规律,为类似地质条件的工作面进行高产、高效、安全生产提供借鉴。
This paper took Dongtan coal mine 3303 fully-mechanized sublevel caving mining working face in FS46 fault nearby track transportation tank as the research background.By combining numerical simulation and field observation method it discussed the 3303 fully mechanized top-coal caving face,the rail in overlying coal seam mining stress distribution during the changing situation.And through the 3203 mining face roadway deformation analysis,the paper analyzed and defined the stress concentration area and further the structure complicated regional mine pressure law appeared,revealed the influence law of the complex geological structure of coal seam mining,provided reference for the working face of the similar geological conditions in high yield,high efficiency,safety production.
