摘要
论述了西峪煤矿瓦斯管理方面存在的不足主要有:对瓦斯涌出规律的研究不深入,瓦斯治理基础工作薄弱;矿井负压较大,主扇在临界区运转;通风系统不合理,通风系统复杂,通风系统稳定性差;"一通三防"方面欠账较多等。针对该矿瓦斯治理工作现状和瓦斯治理中存在的问题,提出加大通风系统改造力度,优化通风系统,做好瓦斯涌出的预测工作,加强对局部积聚瓦斯的处理,推广双风机、双电源自动切换装置,加强瓦斯监控管理,推广瓦斯抽放技术等防治措施。
Discusses that the existing shortcomings of gas management in Xiyu coal mine mainly has the research is not deep on the gas emission laws,the foundation work of gas control is weak.Mine negative pressure is larger,main fan operate in the critical area.The ventilation system is not reasonable,the ventilation system is complex,the stability of ventilation system is poor.＂One ventilation three prevention＂ debts are more.According to the gas treatment situation and the existing problems in the gas management in this mine,puts forward increasing ventilation system reconstruction efforts,optimizing ventilation system,completing the gas emission prediction,strengthens to the local accumulation gas processing,promotes double fan,double power supply automatic switching device,strengthen the gas monitoring management,promotes the prevention and control measures of gas drainage technology and so on.
