赵各庄矿瓦斯综合防治措施

Comprehensive prevention and control measures of gas in Zhaogezhuang Mine

为防止煤与瓦斯突出危险,赵各庄矿积极采取瓦斯综合防治措施,优化矿井通风系统,严格煤与瓦斯突出管理,完善安全监测监控系统,在防突工作中坚持源头治理、超前防治、依法治突、严格管理的理念,实施以保护层开采、岩巷穿层钻孔预抽为主的区域防突措施;瓦斯抽放坚持"一面一策",形成了矿井采前预抽、泄压瓦斯预抽、采后抽采的高低浓度瓦斯抽采系统,做到了应抽尽抽,使工作面回风流瓦斯浓度控制在0.4%以下,杜绝了瓦斯超限、瓦斯积存事故,实现了36 a的一通三防安全生产。

To prevent coal and gas outburst accident, Zhaogezhuang Mine has actively adopted comprehensive prevention and control measures, optimized ventilation system, enhanced coal and gas outburst management, improved safety supervision and monitoring system, sticked to the principles of source control, advanced prevention and control, rule of law and strict management in outburst prevention and implemented regional outburst prevention measures in protection stratum mining and pre-drainage of boreholes crossing rock headway; ＂one policy for each mining face＂is adhered to in gas drainage, forming a high- and low- concentration gas drainage system of pre-drainage, pressure-relief gas drainage and post-mining drainage. Zhaogezhuang Mine has achieved need-based drainage and return air gas concentration is controlled under 0.4%, kept accidents like gas overrun and gas accumulation from happening and achieved 36 a safety production of ventilation and prevention of dust, gas and fire.
