Limestone ore rock more faults, joint fissures and karst development, blasting prone to large blocks, rock walls and roots. This paper introduces the limestone mine of Sichuan Shuangma Cement (Group) Co., Ltd. Through the analysis of the geologic structure, the location and reason of the large block, the rock wall and the basement output, the blasting test research and technical measures are taken and achieved better Blasting effect; as well as the renewal of perforated equipment, the use of stroke pressure portable air compressor air supply equipment system, so that drilling efficiency, energy consumption decline experience for similar mining aids.
