胶轮式定向钻机在煤矿探放水钻孔施工中的应用

Application of Rubber-Wheel Directional Drilling Rig on Water Exploration and Drainage Drilling Construction in Coal Mine

针对具备无轨运输条件的煤矿井下探放水孔密集、成孔精度高和钻机快速搬迁和降低工人劳动强度等需求,开发了胶轮式定向钻机。介绍了该钻机的组成及基本参数,并在布尔台煤矿进行了现场试验。试验结果表明,该钻机机动性强,1人可完成搬迁,极大降低了工人的劳动强度,提高了工作效率;在探放水孔施工中性能稳定,命中率高,各项参数达到设计要求,为同类矿井钻孔施工奠定了基础。

In view of the requirements of dense underground water exploration and drainage hole,high hole forming accuracy,rapid drilling rig relocation and reducing labor intensity in coal mine with trackless transportation conditions,a rubber-wheel directional drilling rig was developed.The composition and basic parameters of the drilling rig were introduced,and the field test was carried out in the Buertai coal mine.The test results show that this drilling rig has high mobility,can be moved by one worker,greatly reduces the labor intensity of workers and improves work efficiency.It has stable performance and high hit rate in the construction of water exploration and drainage hole,and various parameters meet the design requirements,which lays a foundation for the construction of similar mine drilling.
