摘要
为提升综采工作面回撤通道的支护效果和液压支架的回撤效率,保证工作面高产高效生产,在对1209工作面地质条件及巷道布置研究的基础上,分别对回撤通道停采让压和回撤期间的矿压显现规律进行分析,并对单向和双向回撤方案进行对比,最终采用双向回撤技术完成工作面的回撤任务。
In order to improve the support effect and hydraulic support recovery efficiency of fully mechanized mining face and ensure high yield and high efficiency production of working face,on the basis of the study of geological conditions and roadway layout of 1209 working face.This paper analyzes the law of mine pressure during withdrawal and withdrawal,and the one-way and two-way withdrawal schemes are compared.Finally,the two-way withdrawal technology is used to complete the withdrawal task of the working face.
