In the actual mining work, the application of geological exploration technology can greatly improve its work efficiency. However, its safety cannot be ignored, it will directly affect the development of geological exploration. All along, our country has abundant mineral resources, which can effectively promote the improvement of our country's social and economic level. Mineral resources are non-renewable energy, so the best exploration technology should be used in the mining and use of mineral resources, so as to achieve the purpose of orderly development of the whole work.展开更多
