摘要
根据煤田与围岩存在密度差,会引起重力异常的实际情况,本文采用重力法进行煤田勘探,首先分析了重力勘探的可行性,然后在介绍了拉格斯特重力仪工作原理和技术指标的基础上,使用拉格斯特重力仪进行了煤田勘探,研究了煤田重力勘测的工作过程以及对重力异常的校正。
According to the density difference between coal field and the rocks around,it will lead to the actual abnormal situation of gravity.In this paper,the gravity method for coal exploration is used.Firstly,it analyzes the feasibility of gravity exploration,and then based on the Lacoste .Romberg gravity meter work principle and technical index,it uses L-R gravimeter coalfield exploration to do the research work in coal gravity survey and the gravity anomaly correction.
