摘　　要：积水采空区是下伏煤层开采的主要突水威胁。在对水体不做处理的条件下,必须通过控制覆岩破坏的高度,使其不导通上覆积水采空区来确保煤层安全开采。以新疆某矿实际地质、采矿条件为依据,在综合考虑多种覆岩控制技术的条件下,选择条带开采作为该矿井的主要开采方法,在尽量提高采出率的前提下确定合理采留宽度,确保煤柱的稳定性,并对条带开采的具体开采工艺进行了优化设计。研究结果表明,该设计方案不仅能使该矿井顺利达产,而且能确保积水采空区下的安全回采。The water in goaf is the main threat of water inrush underlying coal seam mining. In the water without treatment conditions must be controlled by overburden failure height,the height of the conduction of water in goaf to ensure the safety of coal mining.With the actual geological and mining conditions of a mine in Xinjiang as the basis.The advantages and disadvantages of considering a variety of mining methods,selection of strip mining as the main mining method of the mine;trying to improve the recovery rate under the premise to determine the reasonable mining width,ensure the stability of coal pillar in strip mining technology;specific mining optimized design. The results show that the proposed scheme can not only make the the smooth production,and can ensure the water production safety mining empty area.
