综采工作面过断层顶板控制措施研究

Study on Roof Control Measures in Fully Mechanized Mining Face Passing Through the Fault

综采工作面过断层带期间受构造应力影响,断层上下盘附近煤岩体出现破碎现象,若不及时采取合理的顶板控制措施,不仅影响着工作面正常移架,降低了工作面回采效率,而且很容易发生重大煤矿安全事故。本文以西曲矿28302工作面为例,提出了合理有效的工作面过断层顶板控制措施,确保综采工作面安全顺利回采。

When the fully mechanized coal face passes through the fault zone, affected by the tectonic stress, coal and rock mass over ＆ under the plate will be broken. if rational roof control measures are not taken, not only affects the normal movement of the working face, reduces the mining effciency of the working face, but it＇s also easy to lead to major coal mine safety accidents. Taking the working face of 28302 in Xiqu Mine as an example, this paper puts forward reasonable and effective roof control measures of working face passing over fault to ensure the safe and smooth recovery of fully mechanized mining face.
