摘要
目前,我国高瓦斯、高突矿井使用的瓦斯抽采钻机,大多为西安院及重庆院生产的钻机,鉴于其使用费时费力、不能适应大断面巷道均匀布置钻孔的目的,寺河矿决定研制新型的瓦斯抽采钻机,既实现钻孔的全断面布置,并大大减少工人劳动强度。研制实践表明,效果良好,值得推广。
Most drilling rigs for gas drainage in high gas outburst mines are produced by Xi＆#39;an Research Institute or Chongqing Engineering Co., Ltd., CCTEG. Wasting time and energy, the rigs could not adapt to uniform boreholes in large-section roadways. Therefore, Sihe Mine develops a new drilling rig to realize whole-section layout of boreholes and to reduce labor intensity. The practice shows that, with ideal effects, it is worth spreading.
