摘要
根据新汶矿区深部勘探的需要,近年来新矿集团勘探公司在现有设备基础上大胆进行技术改造,采用TXB-1000型千米钻机完成孔深1 500 m以下的煤田勘探超深孔30余个,最大孔深达到1 732.30 m,在挖掘设备潜力、科学安全施工方面进行了有益的探索。
In recent years, according to the deep exploration of Xinwen mine area, Xinwen Mining Group Com- pany makes a great technological transformation on the basis of existing equipment by TXB - 1000 km deep drilling machines, which have completed the holes more than 30 under 1,500 - meter- deep in the coalfield exploration, the biggest deep hole reaches to 1 732.30 m, which is a good approacth to digging in potential atility and scientific and safe construction of equipment.
