摘要
煤矿矿井瓦斯的主要危害形式包括瓦斯喷出、突出、普通涌出以及爆炸,瓦斯具有易燃易爆性和窒息性,是煤矿安全管理的重点.结合煤矿矿井实例,针对以上几种常见危害类型制定出综合性的瓦斯防治技术措施,涵盖涌出量测定、煤层地质钻探、通风、抽放、引排、局部防突、区域防突、爆炸极限控制、引火源控制.在通风安全管理中,重点分析了需风量计算、工作面温度与风速,为系统通风设计提供量化的依据.研究内容较为全面,具有较强的工程指导意义.
Abstract
The main forms of gas hazards in coal mines include gas eruption,outburst,ordinary outburst,and explosion.Gas is flammable,explosive,and suffocating,making it a key focus of coal mine safety management.Based on the examples of coal mines,comprehensive gas prevention and control measures have been developed for the above common types of hazards,including measurement of gas emission,coal seam geological drilling,ventilation,drainage,local outburst prevention,regional outburst prevention,explosion limit control,and ignition source control.In ventilation safety management,the focus is on analyzing the calculation of required air volume,working face temperature and wind speed,providing quantitative basis for system ventilation design.The research content is comprehensive and has strong engineering guidance significance.
