40年来，地质系统累计完成钻探工作量10011万m，坑探工作量400万m，年开动钻机约3000台，钻、坑探队伍近8万人，在我国已探明储量的148种矿种中，应用探矿手段探明储量的占80％，探矿工程已成为地质、勘察工作直接取得地下实物资料和探明矿产储量的重要方法。在近几年来，预算外钻、坑探工作量猛增，1989年预算外钻探工作最高达200多万米，为预算内工作量的140％，创收4亿多元，探矿工程已处于地质市场多种经营队伍的前列。 Over the past 40 years, the geological system has completed a total drilling volume of 100.11 million m, a pit exploration workload of 4 million m, about 3000 drilling rigs per year, nearly 80,000 drilling and pit drilling teams, and 148 proven mineral reserves in China Among them, 80% of the proved reserves are applied by means of prospecting, and the prospecting project has become an important method for directly obtaining the underground physical data and discovering the mineral reserves of the geological and prospecting work. In recent years, extrabudgetary drilling and excavation work surged. Up to 2 million extra-budgetary drilling was conducted in 1989, accounting for 140% of the estimated workload and generating a revenue of more than 400 million yuan. The prospecting project is already in the geological market A variety of management team in the forefront.
