根据地面普通小型挖掘机械工作原理,研制出能适用于煤矿井下有瓦斯等爆炸性气体环境,并适应目前国内大多数井巷断面施工要求,在矿井斜巷或地铁、隧道等狭窄工作面,以及立井井筒工作面施工的小型液压挖掘机械。该项目的研制与应用将对矿井斜巷、立井井筒施工加快速度、提高效率、减轻工人劳动强度起到积极促进作用,也将为今后从事煤矿斜井巷道、立井井筒施工的单位带来很好的技术经济效益。
According to the working principle of common ground small excavation machine, it can be applied to coal mine gas and other explosive gas environment, and to adapt to the current domestic most of the roadway section construction requirements, the mine inclined roadway or subway, tunnels and other narrow face, Small hydraulic excavator with wellbore face construction. The development and application of the project will play a positive role in accelerating the speed of mine inclined shaft and vertical shaft construction, improving efficiency and reducing labor intensity of workers, and will also bring very good results for units that will be engaged in the construction of inclined shafts and shafts in coal mines in the future The technical and economic benefits.
