我队今年以来，在某地区开展了砂金矿的地质普查工作。根据地质工作的需要，选用了以砂矿浅井为主的井探工程。打了深度4—15米的砂井若干个，除个别井因涌水量过大，没有满足地质要求外，其余井均达到了预计深度，取得了一定地质成果。 This year, our team has carried out geological census of gold and gold deposits in some areas. According to the needs of geological work, we chose a well exploration project that is mainly composed of sand and shallow wells. Sand depth of 4-15 meters hit a number of wells, with the exception of individual wells due to influx is too large, did not meet the geological requirements, the other wells have reached the expected depth, and achieved some geological results.
