首钢矿山公司1988年年产矿石1850万吨,采剥总量达7500万吨以上。高效率大型设备的应用,提高了采矿能力,年下降速度加快,公司所属矿山,大部分已转入凹陷开采,水孔数量逐年增加,抗水炸药使用比例和爆破成本呈逐年上升的趋势。为了降低爆破成本,公司于1987年7月购置一台PPC-250型炮孔排水车,并在水厂铁矿使用。一年多的生产实践表明,使用炮孔排水车处理水孔后装铵油炸药爆破与使用抗水炸药相比,节省了炸药费、降低了消耗、提高了爆破质量、减轻了工人的劳动强度、改善了工作环境,具有明显的经济效益和社会效益。
Shougang Mining Co., Ltd. produced 18.5 million tons of ore annually in 1988, with a total mining of 75 million tons. The application of large-scale high-efficiency and large-scale equipment has increased the mining capacity and accelerated at an annual rate of decline. Most of the mines owned by the Company have been switched to sag mining and the number of water holes has increased year by year. The proportion of anti-explosives used and blasting costs have been increasing year by year. In order to reduce the cost of blasting, the company purchased a PPC-250 blasthole drainage truck in July 1987 and used it at the ironworks. More than a year of production practice shows that the use of blasthole drainage after processing water hole blasting ammonium oil explosives blasting compared with the use of anti-explosives, saving explosives costs and reduce consumption, improve the quality of blasting and reduce the labor intensity of workers , Improve the working environment, with obvious economic and social benefits.
