高效快速掘进系统现状及支护设备发展

The current situation of high efficiency and rapid driving system and development of support equipment

近年来随着国家对煤炭产业的调整,各大矿务局都在努力提高巷道的掘进速度,因此对煤巷的快速掘进后配套设备提出更高的要求。针对不同的巷道掘进方式陆续开发中多种类型的锚杆支护设备,针对不同的地质条件先后开发出配套掘进机的两臂锚杆钻车,配套连采机的四臂锚杆钻车和配套掘锚机组的锚杆转载机组,三种配套方式各有优点但相互之间又不能取代,需根据具体的地质条件选择合理的掘进方式。

In recent years,with the adjustment of the national coal industry,the major mining bureaus are trying to improve the tunneling speed of the roadway,so the requirements for the supporting equipment for rapid coal roadway tunneling are getting higher.According to different roadway driving modes,various types of bolt support equipment are developed successivel y.According to different geological conditions,two-arm bolt driller for roadheader,and four-arm bolt driller for cont inuousmining machine and bolt transfer unit for bolt driving unit are developed.Each of the three matching modes has its ow nadvantages,and they can not be replaced by each other.Therefore,it is necessary to select the matching mode according tospecific geological conditions.
