摘 要:瓦斯和水害给煤矿安全生产造成重大影响,随着煤矿开采深度和规模的不断增大,采空区瓦斯从上隅角一带大量涌出,引起上隅角和回风流瓦斯超限问题,以及采空区积水危害日益凸显。目前,随着定向钻进工艺的不断发展与完善,定向钻机在瓦斯抽放和探放水钻孔中被普遍应用。Gas and water hazards have a significant impact on the safety production of coal mine,with the increasing depth and scale of coal mining,the problem of gas over-limit in upper corner and return air flow and the harm of water accumulation in goaf caused by a large amount of gas gushing from the upper corner of goaf are becoming more and more serious.At present,with the continuing development and perfection of directional drilling technology,directional drilling rig is widely used in gas drainage and water drilling.
