摘要:
为有效控制综采工作面瓦斯超限问题、保障矿井安全生产，优化采动卸压瓦斯抽采技术体系。采用二维物理相似模拟试验方法，结合倾斜开采条件下“孔-巷”系统变形率与声发射能量变化规律，研究高抽巷与定向长钻孔的布置参数及抽采口位置；构建综采工作面采动卸压瓦斯“孔-巷”协同抽采技术模型，并基于负压分配优化试验分析最佳抽采参数组合。研究结果表明：高抽巷合理平距为5~7倍采高，垂距为4.48~6.40倍采高；定向长钻孔合理平距为3.4~6.0倍采高，垂距为2.40~4.00倍采高；高抽巷抽采口最优位置为距离切眼52 m处；定向长钻孔与高抽巷负压比例分配为0.9∶14.5~1.3∶17.5时，抽采效率显著提升，瓦斯体积分数可稳定控制在安全阈值以下。研究结果可为高瓦斯矿井采动卸压瓦斯抽采系统设计、参数优化及安全防护技术提供理论支撑与工程实践参考。
Abstract:
In order to effectively control the problem of gas overrun in fully mechanized mining face,ensure the work safety of mine,and optimize the technical system of mining pressure relief gas extraction,using the two-dimensional physical similarity simulation experiment method,and combined with the deformation rate and acoustic emission energy variation law of the “hole-lane” system under the inclined mining conditions,the layout parameters and the location of extraction outlet of the high extraction roadway and directional long borehole were studied.A “hole-lane” collaborative extraction technology model of mining pressure relief gas in fully mechanized mining face was constructed,and the optimal combination of extraction parameters was analyzed based on the negative pressure distribution optimization experiment.The results show that the reasonable horizontal distance of high extraction roadway is 5~7 times of mining height,and the vertical distance is 4.48~6.40 times of mining height.The reasonable horizontal distance of directional long borehole is 3.4~6.0 times of mining height,and the vertical distance is 2.40~4.00 times of mining height.The optimal position of extraction outlet of the high extraction roadway is 52 m away from the open-off cut.When the negative pressure ratio of directional long borehole and high drainage roadway is 0.9:14.5~1.3:17.5,the extraction efficiency is significantly improved,and the gas volume fraction can be stably controlled below the safety threshold.The research results can provide theoretical support and engineering practice reference for the design,parameter optimization and safety protection technology of mining pressure relief gas extraction system in high gas mines.
