深部开采瓦斯时空间协调抽采模式研究

    Extraction Model Research on Space-time Coordination of Gas Deep Mining

    • 摘要: 在分析某矿24060采面“S”型覆岩空间裂隙场内卸压瓦斯涌出规律的基础上,确定了24060采场瓦斯时空间协调抽采模式,采用了上隅角抽采、高位尾巷抽采以及偏“Y”型通风方式等进行瓦斯综合治理,并对上隅角抽采、高位尾巷抽采以及偏“Y”型通风进行了效果评价,得出“S”型覆岩空间裂隙场内的瓦斯抽采主要以高位尾巷和上隅角抽采为主,采空区埋管为辅的抽采模式,有效控制了工作面的瓦斯浓度,保障了工作面的安全高效生产。

       

      Abstract: Based on analyzing the laws of the pressure relief gas which is in "S" type overburden rock fracture space of 24060 working face. The paper established the gas coordination extraction time and space pattern in 24060 stope, and adopted upper-corner gas extraction, extraction from the high-level tail roadway and inclined to "Y" type ventilation mode for gas comprehensive management. The paper designed and evaluated the upper-corner gas extraction, extraction from the high-level roadway and inclined to "Y" type ventilation. It is concluded that the main gas extraction is high-level tail roadway extraction and gas extraction in upper corner, the auxiliary gas extraction is burying pipeline in the goaf and inclined to "Y" type ventilation, which reduces the gas concentration of the working face and ensures the safety and efficient production of the working face.
