受涌水溃砂威胁厚煤层综放开采导水裂隙带发育特征研究
Research on the height of water flowing fractured zone caused by fully mechanized mining with top coal caving of thick seam threatened by water and sand inrush disaster
采矿破坏形成的垮落带和导水裂隙带贯通含水砂层是矿井涌水溃砂灾害发生的直接原因。以运河煤矿7311工作面地质采矿条件为工程背景，利用自主研发的双端封堵测漏装置，对受涌水溃砂威胁的7311工作面综放开采导水裂隙带发育高度进行现场实测，发现垮落带高度为21.8~24.8m，导水裂隙带高度为59.9m；为对比验证现场实测的结果，借助FLAC数值模拟软件又对其进行模拟，发现导水裂隙带高度为56m，与现场实测结果基本相吻合。研究结果对受涌水溃砂威胁厚煤层安全开采具有一定指导意义。
aving zone and water flowing fractured zone caused by mining connecting with water-bearing stratum is the immediate cause of water and sand inrush disaster. Geological and mining conditions of 7311 working face in yunhe coal mine is looked on as the engineering background, the double-block leak equipment developed by SDUST is used to measure the height of water flowing fractured zone caused by fully mechanized mining with top coal caving technology，the height of caving zone is 21.8~24.8m and the height of water flowing fractured zone is 59.9m; To verify the result of field measurement, the height of water flowing fractured zone is also simulated with FLAC, the height of water flowing fractured zone is 56m, which is consistent with the field testing results. The research results have a certain guiding significance for preventing water and sand inrush disaster during coal mining.
