针对目前煤矿井下施工的瓦斯抽采钻孔布孔密集,成孔速度快,钻机搬迁频繁等特点,应用全液压履带钻机能够较好的完成钻孔施工。以最具代表性的ZDY4000L型全液压履带钻机为例,介绍了全液压履带钻机在本煤层瓦斯抽采钻孔施工中的特点,并以山西焦煤集团杜儿坪矿和山西新元公司的实际应用情况为例,阐明全液压履带钻机在本煤层瓦斯抽采施工中的优势,为同类矿井钻孔施工提供借鉴及指导。
In view of the characteristics of dense gas drainage drilling holes, rapid hole formation speed and frequent drilling rig relocation in coal mine construction at present, the application of full hydraulic crawler drilling rig can well complete the drilling construction. Taking the most representative ZDY4000L full hydraulic crawler drill as an example, this paper introduces the characteristics of full hydraulic crawler drilling rig in gas drainage drilling in this coal seam. Taking the actual situation of Du’erping Mine of Shanxi Coking Coal Group and Shanxi Xinyuan Company Application as an example to illustrate the advantages of full hydraulic crawler drilling rig in the gas drainage in this coal seam and provide reference and guidance for the drilling of similar mines.
