为了适应社会主义建设事业对磷矿石的需要,我矿于1970年6月开始,从生产中抽出部分设备、材料和生产工人,自力更生,进行了我矿第一对竖井建设。经过两年多的努力,虽然取得了一定成绩,但由于没有专业施工队伍,技术力量薄弱,施工设备不足,缺乏这方面的管理经验,井下涌水量按原资料提供含水层掘完时才有1700米~3/日,而现在刚进入含水层5米(含水层27.5米厚)就已达到2700米~3/日。由于岩性破碎,经常卡钎,同时又是承压水,打好炮眼也无法装药爆破。一台75瓩吊泵排水已适应不了,井筒断面小,不能增加吊泵数量,工人们站在水中作业,头上淋帮水同下雨一样,劳动条件相当艰苦,这样就无法用普通方法继续施工。1972年4月份,党委发动群众想办法,决定采取注浆法封水,并立即派人去兄弟单
In order to meet the needs of the socialist construction of phosphate rock, mine in June 1970 began to extract some of the equipment from the production, materials and production workers, self-reliance, carried out the first of mine mine shaft construction. After more than two years of hard work, some achievements have been made. However, due to lack of professional construction team, weak technical strength, inadequate construction equipment and lack of management experience in this field, underground water inflows only provide 1700 M ~ 3 / day, and now just entering the aquifer 5 m (aquifer 27.5 m thick) has reached 2700 m ~ 3 / day. Due to the lithology broken, often brazing, at the same time is under pressure water, lay a hole can not charge explosive blasting. A 75 瓩 hanging pump drainage can not adapt to the wellhead section is small, can not increase the number of hanging pumps, workers standing in the water work, head and shower with the same rain, labor conditions are quite difficult, so you can not continue with the usual methods construction. In April 1972, the party committee mobilized the masses to find a solution and decided to adopt the grouting method to seal the water and immediately sent people to go to the fraternal single
