摘要
神华宁夏煤业集团白芨沟煤矿为高瓦斯矿井,瓦斯治理始终是矿井灾害防治的重点,但在2521-1工作面开采中,外围火区的存在及威胁已经有所显现,且随着开采深度的增加,外围火区对工作面开采的威胁却越来越大。目前,对于即将接续开采的2521-2综采工作面,必须提前采取措施,做好通风、瓦斯、高温火源的综合防治,确保矿井"一通三防"安全。
Baijigou Mine of Shenhua Coal Group is a gas intense one. Prevention of gas caused disaster is always high on the agenda. However, during excavation of 2521^-1 working interface, the threat of periphery fire zone has shown a sign, and it seems to get worse with the increase of depth. At the present time, precautions shall be taken in advance for the coming 2521^-2 fully mechanized working interface. Gas and high temperature combustion source must be prevented while ventilation ensured.
