高瓦斯工作面高位抽采巷布置设计与应用

Design and application of high gas working face high gas drainage

针对高河煤矿W4302工作面瓦斯测定参数数值较大的情况,通过分析高位抽采巷的优点和施工工艺后,决定在该工作面布置高位瓦斯抽采巷进行瓦斯抽采。结果表明应用高位抽采巷后,抽采率达到了59.6%,瓦斯超限情况可以得到有效控制,能够满足矿井安全生产需求。

Based on large numerical value of gas determination parameters in W4302 working face of Gaohe Mine,pre-drainage was adopted in high gas drainage position after analyzing the gas drainage condition. The result showed that the drainage rate achieved by 59.6%,with good control of gas overrun and meeting the safe production goal.
