摘要
瓦斯灾害是制约煤矿安全生产的主要矛盾,采用地面钻井抽采瓦斯,是瓦斯治理和煤层气开发的一种有效手段。淮南矿区在松软低透气性的煤层赋存条件下,通过瓦斯治理与采矿技术相结合,通过多年实践,基本明确了地面钻井抽采瓦斯技术的发展方向,其有关成熟做法对地质条件类似的矿区具有借鉴意义。
Gas-related disasters are major contradictions restricting work safety in coal mines. The surface well drilling technology can be a very effective means to control gas and develop coal mine methane （CMM）. Coal seams in Huainan coal mining area are soft with low pemaeability. Years of practice have helped HMC find the right orientation to develop the surface well drilling technology basically by combining gas control and mining technologies. Such proven measures can be of the significance of using for reference by other communities with similar geological conditions.
