冯营矿煤层卸压带宽度浅析

On the Width of Pressure Relief Seam of Fengying Coal Mine

通过对24121运输巷未施工钻孔巷道煤层瓦斯含量的测定和钻孔漏气深度的测定,得出巷道卸压带宽度规律,为合理选择煤层瓦斯抽采钻孔的封孔深度提供了依据,优化了抽采钻孔布置,实现了对煤层瓦斯抽采钻孔的封孔方法的科学管理。

Through the measurement for 24121 coal seam gas content of conveyance road and drilling leakage depth, this paper gets the regulations of the width of pressure relief seam, which provides basis for reasonable selection of coal seam gas drainage depth of sealing hole, optimizes drainage borehole layout, and realizes the scientific management of hole sealing method for coal seam gas drainage borehole.
