天井和平巷掘进设备现在,阿利马克公司推出了新一代天井爬罐,即RCM-6系列爬罐。这种爬罐按每周工作10班,平均掘进速度(40米/周)和每米费用与天井钻机相同,但投资却只相当于天井钻机的20～25％。凿岩速度由于使用全液压凿岩机而加快(每分钟可达2米)。可采用最长为4.2米的任意长度的钎杆,而以前最长为2.4米;同时,采用大直径钎杆能更准确地钻凿炮孔和更好地控制爆破。由于每槽炮的进尺增大,安装时间大为缩短(特别在长
Patio Peace Tunnel Excavation Equipment Now, Alimak has introduced a new generation of patio climbing tanks, the RCM-6 Series Climbing Tanks. This type of canister operates 10 shifts per week, with the same average speed (40 m / week) and cost per meter as the well drilling rig, but invests only 20-25% of the cost of a rig. Rock drilling speed is up to 2 meters per minute due to the use of fully hydraulic rock drill. Drill bars of any length up to 4.2 m can be used, up to a maximum of 2.4 m in the past, while the larger diameter drill rod allows for more accurate drilling and better control of blasting. Due to the increased footage per tank gun, installation time is greatly reduced (especially in the long
