煤矿掘进工作面常见冒顶事故的原因及防治措施

Causes and Prevention Measures of Common Roof Falling Accidents in Coal Mine Excavation Faces

煤矿实际采掘过程中,在各种因素的影响下,很容易发生安全事故,给煤矿企业带来经济损失。其中,冒顶事故是煤矿中比较常见的事故,不仅威胁着施工人员的人身安全,还降低了煤矿的生产质量和效率。主要介绍了掘进工作面冒顶机理、类型及事故发生的可能原因,并且研究了冒顶事故发生征兆及规律。根据实际情况提出了科学合理的防治措施,从而保证掘进工作面的安全。

In the actual mining process of coal mines,under the influence of various factors,it is easy to induce safety accidents and bring economic losses to coal mining enterprises.Among them,roof falling accidents are relatively common accidents in coal mines,which not only threaten the personal safety of construction personnel,but also reduce the quality and efficiency of coal mine production.The mechanism,types,and possible causes of roof falling in the excavation face were mainly,and the signs and regularity of roof falling accidents were studied.Based on the actual situation,scientific and reasonable measures were proposed to ensure the safety of the excavation face.
