煤矿采空区瓦斯爆炸预防技术研究

Research on Prevention Technology for Gas Explosion in Mined-out Area

针对兖矿新疆矿业有限公司硫磺沟煤矿采空区复杂的环境条件,对不同温度、不同压力条件下的瓦斯爆炸界限进行了实验研究,得出采空区环境条件下的瓦斯爆炸界限值与瓦斯爆炸界限随环境压力及环境温度的变化规律。在此基础上提出了预防矿井采空区瓦斯爆炸事故的安全对策措施,可为类似矿井提供有效的预防手段,从而保障矿井的安全生产。

In this paper,experimental study was carried out on the gas explosion limits at different temperatures and different pressures in accordance with the complicated environmental conditions in the mined-out area in Liuhuanggou Coal Mine of Xinjiang Mining Corporation of Yankuang Group,and the gas explosion limit values under the mined-out area condition and their variation regularity with the ambient temperature and pressure were obtained.On this basis,safety measures for preventing gas explosion in mined-out area was proposed,which can provide an effective means for the explosion prevention in the mined-out area of the similar coal mines and thus guarantee safe production of the mine.
