回顾解放前伪“资源委员会”时期，仅有十几台外国手把立根钻机、沙利文人力手摇钻及水压给进钻探机等，从事东北小丰满水电厂钻探灌浆和长江三峡等处进行极少量水电钻探工作。据不完全统计，年总钻探进尺仅四千五百米左右。新中国成立后，在党的领导下，十分重视水电资源开发，迅速创建和发展壮大了水电工程地质钻探事业。当前已有约四十个地勘队（指部直属单位，不包括省设计院），开动岩心钻机二百余台，年钻探总进尺达十六万米。现将其发展情况及主要成就简述如下：
During the period before liberation, only a dozen foreign handlers took root drilling machine, Sullivan manpower hand drill and water pressure feeding drilling machine, etc., to engage in drilling grouting in the Northeast Fengman Hydropower Plant and the Three Gorges of the Yangtze River Very few hydro drilling jobs. According to incomplete statistics, the annual drilling footage is only about 4,500 meters. After the founding of New China, under the leadership of the party, great attention has been paid to the development of hydropower resources and the rapid establishment and development of hydrogeology and geological drilling projects. Currently there are about 40 geological exploration teams (directly under the Ministry of the Ministry of units, not including the Provincial Design Institute), drilling more than 200 sets of core drilling rig, drill total footage of 160,000 meters. Now its development and major achievements are summarized as follows:
