补连塔煤矿22310综采面回采经验分析

Mining experience analysis of 22310 fully mechanized face in Bulianta Coal Mine

针对大采高综采工作面回采过程中顶板压力大、顶板控制难、出现底鼓难等一系列现场管理难题。以补连塔煤矿大采高综采工作面为例,介绍了7 m大采高综采工作面回采过程中支架工作阻力确定方法、顶板管控办法、末采贯通顶板控制。为类似地质条件的大采高综采工作面顶板管理提供一定的借鉴。

Aimed at a series of field management problems such as high roof pressure,difficult roof control and floor heave in the process of fully mechanized face with large mining height.Taking Bulianta Coal Mine as an example,this paper introduces the determination method of working resistance of support,roof control method and roof control in the process of fully mechanized face with 7 m mining height.It provides a certain reference for the roof management of fully mechanized face with large mining height under similar geological conditions.
