摘　　要：为实现精确调节煤矿坑道钻探钻机姿态,以满足钻孔设计的方位角、高度和角度等定位参数,确保钻孔走向精度,利用智能控制技术、电液比例控制技术,设计了煤矿坑道钻机开孔定位参数自动调节系统。基于钻机变幅机构的运动学模型,研究钻机的开孔定位调节控制原理及控制策略,基于控制需求设计了系统软硬件。试验表明:所设计的煤矿坑道钻机开孔定位参数自动调节系统,可以根据操作人员输入的参数,自动完成钻机开孔定位参数的调节,参数误差可以控制在钻孔施工许可的范围之内,相对于人工调节,该系统操作安全便捷,提高了工作效率。In order to realize an accurate attitude alignment of an exploration drilling rig in a coal mine roadway,and to meet the designed azimuth,height,angle and other positioning parameters and to ensure the strike accuracy of the borehole,an intelligent control technology and electro-hydraulic proportional control technology were applied to design the automatic control system of the borehole positioning parameters for the drilling rig in the coal mine roadway. Based on the kinematics model of the luffing mechanism in the drilling rig,a study was conducted on the positioning adjustment control principle and control strategy of the borehole drilling. Based on he control requirements,a system software was designed. The test showed that the designed the automatic control system of the borehole positioning parameters for the drilling rig in the coal mine roadway,according to the input parameters by the operation personnel,could automatically complete the adjustment of the borehole positioning parameters for the drilling rig. The parameter error could be controlled within the construction allowed scope of the borehole. Compared to the manual adjustment,the operation of the system would be safety and convenient and could improve the working efficiency.
