摘　　要：随着凤凰山矿开采年限的增加,煤炭储量日益减少,为提高煤炭资源回收率,减少煤炭丢失,凤凰山矿对盘区煤柱进行了回收。在总结传统过风桥技术的基础上,通过对凤凰山矿二水平煤柱回收综采工作面过风桥技术研究,提出了相应的解决措施和预防办法,保证了煤柱回收工作的正常回采,其研究结果为类似条件下的回采提供了借鉴。With the increase of the mining years of Fenghuangshan Coal Mine,coal reserves are decreasing.In order to improve the recovery rate of coal resources and reduce coal loss,Fenghuangshan Coal Mine has recovered the coal pillars in the area.On the basis of summarizing the traditional over-wind bridge technology,through the research on the technology of the recovery of the fully mechanized mining face over the wind bridge by the two horizontal coal pillars of Fenghuangshan Coal Mine,the corresponding solutions and prevention methods are proposed to ensure the normal recovery of coal pillar recovery work.The results of the study provide a reference for mining under similar conditions.
