摘　　要：为确定小保当一号矿井112201首采工作面最合理的停采线位置,以首采工作面临近末采的地质条件(夹矸赋存)、巷道布置等情况为基础,提出了2种技术方案,同时针对这2种方案存在的问题分别给出了相应的技术措施,并进行了对比分析,最终以安全高效生产为前提,最大限度提高煤炭回收率为原则,选择了最合理的停采位置实施方案。In order to determine the most reasonable stoppage position of 112201 the first mining face of Xiaobaodang mine,based on the geological conditions near the first mining face and the roadway layout,two technical schemes are put forward, and corresponding technical measures are given to solve the problems of the two schemes, and comparative analysis is made,finally, based on the premise of safe and efficient production and the principle of maximizing the recovery rate of coal, the most reasonable stoppage position implementation plan was selected.
