典型案例江西立春坦铌矿,是一家建矿30余年的国有企业,年采矿量约80万吨,在过去,该矿必须使用4台55kw的YQ-150潜孔钻机同时工作,风源供给至少要2台250kW的空压机同时工作,实行214h轮班作业,才能满足矿山开采穿爆要求,操作、维护人员30余人,年钻机穿孔作业耗电量约260万度,电费高达130余万元。2003年,该矿改用1台SWDA165液压潜孔钻机替代4台YQ-150潜孔钻机进行穿孔作业．改用这台装机总容量为240kW的SWDA165液压潜孔钻机后,每天仅需工作一班8小时就可以满足矿山开采穿爆要求,操作、维护仅需6名工作人员。年钻机穿孔作业耗电量仅为60万度左右,电费仅30余万元。该矿山穿爆系统改用SWDA165液压潜孔钻机后,每年仅钻机电耗一项就降低了成本100万余元。
Typical Case Jiangxi Lichun Tanobium Mine is a state-owned enterprise that has built more than 30 years and has an annual mining capacity of about 800,000 tons. In the past, the mine had to use 4 sets of 55kw YQ-150 DTH drilling rigs to work simultaneously with at least one wind source To 2 250kW air compressor at the same time work, the implementation of 214h shift work, to meet the mining requirements of mining explosion, operation, maintenance personnel more than 30 people, annual drilling rig power consumption of about 2.6 million degrees, electricity up to 130 million. In 2003, the mine instead used a SWDA165 hydraulic DTH drilling rig instead of four YQ-150 DTH drilling rig drilling operations. Switch to this installed capacity of 240kW SWDA165 hydraulic DTH drilling rig, only 8 hours a day to meet the mine drilling requirements, operation, maintenance only 6 staff. Drilling rig drilling operation power consumption is only 600,000 degrees, electricity costs only 30 million. After the mine explosion blasting system was switched to the SWDA165 hydraulic downhole drilling rig, the annual power consumption of drilling rig alone reduced the cost by 1 million yuan.
