摘要
根据开挖施工和地压监测取得的实际资料，系统分析了链子崖煤层采空区自然填充的物质成分，不同地段填充程度及相应的地压分布规律。
The data from engineering digging and monitoring are analyzed systematically and some laws of coal cinder composition and its filled extent are correspondingly charac-terized with geopressure distribution in the coal mined-out area at the bottom of Lianzi’ aidangerous rockbody in this paper.
