摘要
针对阳煤集团新景矿3214工作面地质条件,对采煤工作面沿空留巷专用支护系统进行研究,提出沿空留巷专用支护系统选型设计原则,对充填过渡支架和挡矸支架优化设计,并进行井下工业性试验,确保了3214工作面沿空留巷充填开采工艺成功实施,实现工作面Y型通风,有效解决了隅角瓦斯积聚和超限问题,对解决回采工作面巷道布置、减少巷道掘进量、提高采区采出率、减少工作面准备时间、降低开采成本等具有重要意义。
Based on geological condition of3214working face in Xinjing coal mine of Yang coal group,specific supporting system for god side entry retaining of coal face was studied systematic,and then specific supporting system selection and design principle of god side entry retaining was put forward,god side entry retaining filling mining technology of3214working face was processed successfully,and then Y type ventilation of working face was realized,industrial test in the pit was proceeded,some problems that corner gas accumulation and ultralimit were solve successfully,it was significant for roadway layout of working face,decreasing roadway tunneling,improving mining ratio,decreasing release time of working face and reduce mining cost
