近年来各地采用坑道钻找矿代替部分坑探和节约钻探进尺，显示出较好的经济效益，越来越广泛地受到重视。坑道钻施工前，首先应在井下开凿安装钻机、钻塔的硐室。俗称“机窝”其规格的设计和开凿方法，安全、质量，支护结构直接关系到井下钻探的施工速度和安全生产。我队自81年底开始井下钻探施工，对机窝规格的设计和开凿，作了大量的工作，初步形成一套较完整的设计和开凿规范，现简要介绍如下：
In recent years, tunnel excavation around the mine to replace part of pit exploration and save drilling footage, showing good economic returns, more and more attention. Tunnel construction before drilling, first of all should be drilled in the underground drilling rig, drilling tower chamber. Commonly known as “machine nest” its specifications design and cutting method, safety, quality, support structure directly related to the underground drilling speed and safety of production. My team has been drilling downhole construction since the end of 81, a lot of work has been done on the design and development of the machine frame specifications, and a set of more complete design and cutting rules has been initially formed. The brief introduction is as follows:
