地质前探轻便高效钻机的研制与应用

Development and Application of the Portable Efficient Drill for Preliminary Geological Exploration

摘要:

为了确保煤矿井下采掘工作面施工安全，防止因地质条件不清造成安全生产事故，需对施工前方进行地质前探。淮南矿区原来使用的地质前探钻机由于功率太小或搬迁困难，不能很好地满足地质前探钻孔施工需要。以中煤科工集团西安研究院有限公司生产的ZDY1200S型全液压坑道钻机为原型，对其液压系统和主要零部件进行优化设计，以满足地质前探的使用要求。经过现场试验，应用效果良好。

Abstract:

To prevent the accidents caused by unclear geological conditions and ensure the construction safety at mining face, preliminary geological exploration should be done. The originally used underground drilling machine could ont satisfy the need of preliminary geological exploration because of the small power and difficult relocation. Taking ZDY1200S full hydraulic underground drilling machine as a prototype, the design of hydraulic system and main components are optimized to meet the application requirements of preliminary geological exploration. The field test proves the good effect.
