回采工作面断层构造区域顶板控制技术研究及应用

Research and Application of Roof Control Technology in Fault Structure Area of Mining Working Face

为防止采煤工作面通过断层期间发生顶板冒落,在充分分析断层构造影响范围及影响程度的基础上,采取合理调采、控制截割角度及采高、延伸支架支护等措施,使得断层区域顶板得到有效控制,工作面安全通过断层区域。

In order to prevent the roof caving during the coal mining working face passing through the fault,on the basis of fully analyzing the influence range and degree of the fault structure,some measures are taken,such as reasonable adjustment of mining,control of cutting angle,mining height,extended support and so on.So that the roof of the fault area can be effectively controlled and the working face passes safely through the fault area.
