依据辛安矿设计巷道沿积水采空区掘进，且大量积水威胁巷道掘进安全的水文地质条件，对2个拟定施工方案的经济技术参数综合比较，合理选取了“留小煤柱，当日疏水，当日掘进”的施工技术方法。在施工中，通过控制日掘进进度，将煤柱及掘进工作面承受最大静水压力控制在2 m水柱以内，实现了“一班疏水+两班掘进，三班排水” 的生产正规循环组织。全区段巷道掘进达到了5 m /日以上的安全快速新水平，为类似情况掘进工作面的设计、施工组织提供了技术经验借鉴。
Based on water goaf mining and water threatened safe mining in Xin’an Mine, economic parameters of two construction plans were compared, with small coal pillar, mining and dewatering on that day technology was settled. The maximum hydrostatic pressure of coal pillar and mining working face was controlled in less than 2 m water column by checking day mining, No. 1 group dewatering + No. 2 group mining, No. 3 group dewatering team work was set. The roadway mining achieved at 5 m per day, the technology provided technical reference for similar working face design and mining.
