矿井反风演习的实践与解析

    Practice and analysis of mine anti-wind exercise

    • 摘要: 从低瓦斯矿井在反风演习过程中暴露出的多个采掘工作面大面积超限报警、掘进工作面高值爆表超限时间较长、未达到反风演习时间等问题出发,分析了主要通风机类型对矿井反风的影响、开拓系统对正向通风和反风通风的影响、高瓦斯矿井及煤与瓦斯突出矿井反风时的风险、多风井矿井反风时的风险;指出了在部门规章和行业标准及其对反风演习及风量要求和瓦斯浓度控制等几方面存在的制度缺失;提出了建立反风演习复盘机制、规范反风演习通风设施管理、鼓励企业制定反风演习企业标准、列入国家科技攻关计划、修订部门规章和行业标准的相关条款等建议。

       

      Abstract: Starting from the problems exposed in the process of anti-wind exercise in low gas mine, such as large-area over limit alarm of multiple mining faces, long over limit time of the excavation face, and failure to reach the time of anti-wind exercise, the influence of main ventilator types on mine anti-wind, the influence of development system on forwarding ventilation and anti-wind ventilation, the risk of anti-wind in high gas mines and coal and gas outburst mines, and the risks of anti-wind in multi-shaft mines are analyzed. It pointed out that there are institutional deficiencies in departmental regulations and industry standards, as well as the requirements for anti-wind exercises, air volume, and gas concentration control. Suggestions were proposed such as establishing a review mechanism of anti-wind exercise, standardizing the management of anti-wind exercise facilities, encouraging enterprises to formulate anti-wind exercise enterprise standards, including relevant provisions of national science and technology research plans, and revising departmental regulations and industry standards.
