摘要
高瓦斯矿井大采高工作面采用一次采全高的方法回采时经常出现配套设备不符合采高要求,回采时工作面瓦斯涌出量大控制困难以及回采后顶板破碎难以维护等难题,从而影响着大采高综采工作面回采效率,对此潞安集团左权阜生煤业有限公司综采队通过分析研究,对1101工作面回采工艺进行优化设计,实践证明1101工作面优化后的采煤工艺提高了工作面回采率,加快了回采速度,保证了工作面回采安全,取得了显著成效。
using a method of mining full height often appear when equipment does not meet the high requirements of mining working face withlarge mining height in high gassy mine, mining working face gas emission control and difficult recovery after the broken roof is hard to maintainand other problems, thus affecting the efficiency of coal mining working face mining, this Lu＇an Group Zuoquan Fusheng coal limited mecha-nized mining team through analysis and research, optimize the design of the 1101 working face mining technology, mining practice proved thatthe process optimization of 1101 working face has improved working face recovery rate, to speed up the mining speed, toensure the safety of mining, and achieved remarkable results.
