The design and analysis of the MKF-2 type drilling rig

摘要: 介绍了MKF-2型煤矿短钻孔瓦斯抽放施工用钻机的研制原则和思路,详细分析了这种新型钻机的机械结构和液压系统。现场试验表明,这是一种适于井下工作面钻进瓦斯预抽放短钻孔的轻便高效钻机。

Abstract: This paper introduced the design principle and thought way of MKF-2 type drilling rig especially for gas extraction in underground coal mine. The rig's mechanical structure and hydraulic pressure system were introduced in details. The field test indicated that the developed drilling rig is appropriate for underground pre-drainage of coal seams.
