我队鑽探大部在山区施工,由于水源缺乏,孔內漏水严重,加之送水設备不足,因之严重限制了鑽探生产。为此,在党政領导的大力支持和具体帮助下,我们学习了他单位以风代水鑽探的经验,于7号孔试用,通过二十天的曲折摸索,終于胜利完成第一个試驗鑽孔。该孔竣工孔深为69米,所鑽1至20米为浮土和风化岩层,20至30米为矽嘎岩,30至50米为石灰岩,50至69米为磁鉄矿、大理岩和角岩及矽質大理岩。该孔漏水严重,孔内稳定地下水面在45米左右。岩石可鑽 Most of my team drilling in the mountains construction, due to lack of water, hole serious water leaks, coupled with inadequate water supply equipment, which severely limits the drilling production. To this end, with the strong support of the party and government leaders and with the specific help, we learned from his experience of drilling on behalf of the Wind Wind and tested it on Hole No. 7. After twenty days of twists and turns, he successfully completed his first experiment drilling. The hole was completed with a hole depth of 69 meters. Drilled holes of 1 to 20 m were flooded and weathered rock formations, 20 to 30 m of which were igasites, 30 to 50 m of limestone, 50 to 69 m of magnetite ore, marble and angle Rock and Silica Marble. The hole is a serious water leak, the hole in the stable groundwater at about 45 meters. Rock can drill
