| 摘 要： | 由于高瓦斯矿井中,无煤柱沿空留巷Y型通风比传统的U＋L、U型通风方式更有利于解决工作面瓦斯超限、缓解生产衔接紧张等问题,基于此,介绍了屯兰矿沿空留巷Y型通风技术在18205采煤工作面的应用效果,结果表明采用沿空留巷Y型通风技术后,工作面通风能力和安全生产可靠程度大幅提升。同时,通过实施底板瓦斯抽采,消除了18205工作面底板瓦斯涌出的现象,工作面风排瓦斯涌出量下降3~4 m3/min,较未实施底板瓦斯抽采前下降了15%~20%,工作面瓦斯抽采率由60%提高到70%以上,工作面底板及回风瓦斯体积分数均稳定在0.5%以下,瓦斯治理效果良好。

| Abstract: | Due to the Y type ventilation in the pillarless gateway along the goaf of the high gassy mine could be favorable to solve the gas over limit of the coal mining face and gently release the production connection tension and others than the conventional U+L and U type ventilations,the paper introduced the applied results of the Y type ventilation technology to the gateway retained along the goaf of No.18205 coal mining face in Tunlan Mine.The results showed that after the Y type ventilation technology applied ... |
