摘要
为了适应反井钻机施工技术的发展需要,煤炭科学研究总院建井研究分院研制出电液比例控制BMC400型反井钻机,从而实现恒压钻进导孔和扩孔,有效地提高了钻孔精度和钻进效率。文章介绍了该反井钻机电液比例控制系统的设计及其技术特点。
In order to adapt to the needs of the raise-boring technology development, the new type of BMC 400 raise boring machine with electro-hydraulic proportional control system is developed by China Coal Research Institute (CCRI), which could achieve constant pressure in drilling pilot holes and reaming, and effectively improve the accuracy and efficiency of drilling. This paper introduces the system design and technical features of electro-hydraulic proportional control system for raise boring machine.
