为防止瓦斯事故,在《煤矿安全规程》中规定:低沼气矿井所有采掘工作面,对沼气和二氧化碳浓度每班至少检查两次;瓦斯检查人员必须执行瓦斯巡回检查制度。在《矿井通风质量标准及检查评定办法》中又进一步明确要求:所有矿井都要执行一炮三检查制度。如何采取改进措施,杜绝《规程》规定中的漏检是有待解决的问题。关于低沼气矿井瓦斯巡回检查方法根据《规程》规定,目前全国低沼气
In order to prevent gas accidents, the “Coal Mine Safety Regulations” stipulates that: All low-methane gas mining work face, biogas and carbon dioxide concentration at least twice a class inspection; gas inspectors must implement gas inspection system. In the “mine ventilation quality standards and inspection and evaluation methods” and further clear requirements: all mines have to implement one cannon three inspections system. How to take improvement measures to eliminate the “missing” in the “rules” is a problem to be solved. About Low Biogas Gas Methane Patrol Inspection Method According to the regulations, the current low biogas
