1965年5月到9月,我们在内蒙古赤峰红花沟矿区黄土层中进行了浅井压缩爆破试验,由于得到内蒙古地质局和201地质队的积极支持和协助,已成功的用于生产,共完成了八个生产井,进尺116.97米,工班效率比手工挖掘提高1.66—3.89倍,成本降低10%—39.8%,大大减轻了工人的体力劳动。通过这次试验,探索到了黄土中压缩爆破成井的规律及爆破参数,井口可以保持完整,井壁状况良好,井径一般达到0.8—1米,消除了“壶口”现象,不用修壁,出土量很少。
From May to September 1965, we conducted a shallow well compression blasting test in the Honghuagou mining area in Chifeng, Inner Mongolia. Due to the active support and assistance from the Inner Mongolia Geological Bureau and the 201 Geological Team, we have successfully completed the production The eight production wells, footage of 116.97 meters, the efficiency of work shifts than manual mining increased 1.66-3.89 times, the cost of 10% -39.8%, greatly reducing the manual labor. Through this experiment, the law and blasting parameters of compression blasting into loess in loess are explored. The wellhead can be kept intact and the well wall is in good condition. The well diameter generally reaches 0.8-1m, eliminating the phenomenon of “spout”, eliminating the need for repair and excavation Very little.
