综采工作面瓦斯超限现象时常发生,严重制约煤矿的高产高效,同时给煤矿的安全生产带来重大隐患。为掌握某矿1201综采工作面瓦斯涌出分布特征及影响瓦斯涌出的开采技术条件,确保综采工作面安全生产,笔者对该采面瓦斯涌出构成及来源和影响因素进行了分析比对,得出了该采面瓦斯涌出的分布特征,为该综采面的通风管理及瓦斯治理提供了必要的技术指导。
The phenomenon of gas overrun in fully mechanized coal face often occurs, which seriously hinders the high yield and high efficiency of coal mines and brings about significant hidden danger to the safety of coal mines. In order to grasp the gas emission distribution characteristics of 1201 fully mechanized coal face and the technical conditions of mining that affect the gas emission and ensure the safe production of fully mechanized coal mining face, the authors analyzed the composition, sources and influencing factors of gas emission from the mining face The distribution characteristics of the gas emission from the mining face are obtained, which provides the necessary technical guidance for the ventilation management and gas treatment of the fully mechanized mining face.
