不规则边界综采工作面调斜开采技术

Inclination Adjustment Mining Technology of Fully Mechanized Coal Mining Face with Irregular Boundary

不规则边界是煤矿工作面回采经常遇到的情况,运用调斜开采技术调整工作面端头进尺,确保工作面和顺槽顺直,对于提高煤炭资源回收率有着重要意义。结合A矿井不规则边界综采工作面调斜开采,从调斜巷道设计、回风顺槽扩帮与补强支护、调斜开采技术工艺方面,对调斜开采技术的实现进行了探讨。结果表明,该调斜开采技术在保证安全推采的同时,大大提高了煤炭资源回收率,对指导类似工作面回采具有一定借鉴意义。

Irregular boundary is often encountered in coal mining face.It is of great significance to improve the recovery rate of coal resources to adjust the end footage of working face by using inclination adjustment mining technology to ensure that the working face and the groove are straight.Combining with inclination adjustment mining of fully mechanized mining face with irregular boundary in A Mine,this paper discussed the realization of inclination adjustment mining technology from the aspects of design of inclination adjustment roadway,enlargement and reinforcement support of air return way and the process of inclination adjustment mining technology.The results show that,while ensuring safe mining,the inclination adjustment mining technology greatly improves the recovery rate of coal resources,and has certain reference significance for guiding the mining of similar work-ing faces.
