最重要的新型大量开采方法之一是VCR法。成功的应用VCR法需要比一般直径大,深而且精确的炮孔。为满足这一要求,研制了连续开采系统的精巧的潜孔凿岩台车CD系列,其紧凑的尺寸可在低矮空间凿岩,并且部件能分开以便进入难于到达的地点。 One of the most important new large-scale mining methods is the VCR method. Successful application of VCR method than the average diameter of large, deep and accurate hole. To meet this requirement, CD series of ingenious downhole rock drilling rigs for continuous mining systems have been developed that are compact in size and can be drilled in low-lying areas and can be separated for access to hard-to-reach locations.
