地质部勘探技术研究所和我局416队,于1964年10月初开始,在风化白云质灰岩及风化砂岩土质层中进行了压縮爆破成井的試驗。經过两个多月,試驗了32个小圆井,完成工作量140米,工程质量均达到地质要求。在初步掌握了压縮成井的基本操作技术之后,1965年該队继续在施工工区,全部采用压縮爆破成井的方法,在一个半月中,共完工52个小圆井,完成工作量438.37米,平均井深8.4米,最深达18米。效率比1964年提高131％,比人工挖掘提高288％,最高工效記录是6米。单位成本也
The Institute of Exploration Technology of the Ministry of Geology and the 416th Bureau of our bureau started the experiment of compressive blasting into wells in weathered dolomitic limestone and weathered sandstone soil layers at the beginning of October 1964. After more than two months, 32 small wells were tested and the workload was 140 meters. The quality of the project met the geological requirements. After initially mastering the basic operation technology of compression into wells, in 1965, the team continued to use compressive blasting to complete wells in the construction work area. In a month and a half, a total of 52 small round wells were completed with a work volume of 438.37 meters, The average depth of 8.4 meters, the deepest up to 18 meters. Its efficiency is 131% higher than that in 1964, an increase of 288% over manual excavation and the highest ergonomic record is 6 meters. Unit cost also
