摘要
随着我国煤矿开采的深入,特别需要具有效率高、钻孔直径大而且深,并且使用和操作上简单安全的钻机。为了有效地满足煤矿企业生产的需要,加强对气动架柱式钻机的研究具有重要的经济意义和现实意义。
With the deep mining of coal mine in our country, especially to has the advantages of high efficiency, large hole diameter and depth, and at the same time use and operation is simple and safe drilling rig. In order to meet the needs of coal mine production, and has important economic significance and the practical significance to strengthen the research on dynamic post drill for gas.
