钻探工程是当今地质找矿的重要手段,也是地质勘探部门的一个重要组成部分.它占用的投资比例大,花费的人力、物力多.根据冶金地质历年的统计资料,投入钻探工程的资金约占地质勘探总投资的30%,从事钻探工作的人员(包括直接为其服务的人员)约占40%.钻探速度的快慢,质量的好坏,成本的高低,对地质找矿成果和整个地质勘探工作的经济效益,有着直接的影响.因此,要正确地理
Drilling project is an important means of geological prospecting in the present day and also an important part of the geological prospecting department.It occupies a large proportion of investment and takes more manpower and material resources.According to the statistical data of the metallurgical geology over the years, 30% of the total investment in geological prospecting and about 40% of those engaged in drilling (including those directly serving for them). The speed of drilling, the quality of the drilling, the cost of the drilling, the geological prospecting results and the geological survey The economic benefits of work have a direct impact
