大倾角俯斜综采过陷落柱技术研究与实践

Research and Practice on the Technique of Overtaking Collapse Column in Fully Mechanized Mining with Large Dip Angle and Inclined Slope

以金晖隆泰矿井田为例,在介绍该井田工作面的基础上,进一步探索和分析了25°~30°大倾角俯斜综采工作面的回采工艺、技术研究及其可行性,为今后类似条件下工作面的开采提供理论依据和生产实践指导,以解决大倾角俯斜开采对机械化开采的限制问题。

Taking Jinhui Longtai mine field as an example,on the basis of introducing the inclined coal seam,this paper further explores and analyzes the mining technology of 25°or 30°inclined fully mechanized coal face.The technical research and its feasibility provide theoretical basis and production practice guidance for mining face under similar conditions in the future,and solve the problems of limits of overdip fully mechanized mining.
