摘　　要：本文对CSIR采矿技术组正在开展的一个整体研究计划成果进行了评述。该计划的目标在于对集中采矿进行重大改革，任其工作面的推进速度比现有速度提高20倍。考虑了连续无爆破采矿或地下岩石破碎新工艺与水平水力运输在穿脉、运输平巷及最终水力提升之间的相互作用，提出了地下破碎矿脉和掘进废石的新技术，以及一种富有创造性的适合于粗碎岩石水力输送的泵送系统。重点介绍了电震波破碎南非金矿脉和废石样品的破碎技术。富有创造性的TORE系进系统似乎非常适宜于电震波破碎岩石的连续水力运输，其固体质量浓度在45％至67％之间。The paper reviews the results to date of an integrted research programme currently being conduct ed by CSIR Mining Technology,aimed at impacting significantly on concentrated mining with face advance rates of up to 20 times faster than presently achieved. Consideration is given to the interplay between innovative technolOgles for continuous non-explosive mining or rock comminution underground and lateral hydraulic transportation in cross cuts,haulages and eventually hydrouisting. Novel technologies for underground comminution of reef and development waste and an innovative pumping system suitable for the hydraulic transportation of coarse comminuted rock are reviewed. Emphasis is plced on South African gold mine reef and waste samples comminuted by electric shock wave comm in u tion technology.The innovtive TORE pump system appears to be well suited for the successful hydraulic transportation of rock,preduced by,electric shock wave comminution,at solids concentrations between 45 %and 67 %by mass.
