煤矿综放工作面顶板支护安全管理研究

Safety Management of Roof Support of Fully-mechanized Caving Face in Coal Mine

在煤矿开采中,综放工作面顶板容易出现下沉、断裂及支架下滑等诸多安全隐患,为确保煤矿开采的安全稳定性,煤矿企业需要加强对工作面顶板的安全管理工作。基于此,以一煤矿713下05工作面为研究对象,通过监测该工作面矿压情况,为顶板的管理工作提供技术参数支持。结合工作面顶板所需支护强度,科学选择支架型号,并针对不同条件下的顶板情况,提出了相应的安全管理对策。

In coal mining,the roof of fully-mechanized caving face is prone to many safety hazards such as subsidence,fracture and support slide.In order to ensure the safety and stability of coal mining,coal mining enterprises need to strengthen the safety management of the roof of the working face.Based on this,the 713lower05 working face of a coal mine was taken as the research object,and the technical parameter support for the roof management was provided by monitoring the ore pressure of the working face.According to the support strength required by the roof of the working face,the support type was selected scientifically,and the corresponding safety management countermeasures were put forward according to the roof conditions under different conditions.
