The Exploration Of Superseding Resources Prospecting In Crisis Mines Method In China

Bulk minerals in China depend on the foreign increasingly. Meanwhile, imbalance between supply and demand of ore resources is more and more extruded which makes the geological prospecting work urgent. Among them, it has become a hot issue in the area of geology that research on the succeeding in crisis mine resources. Taking Lala copper mine in Huili County, Sichuan Province as an example, the author gets following conclusions:The current succeeding resources prospection in China is urgent, but its development momentum is well. It’s beneficial for the scientific development of mine prospection theory that concluding the suitable crisis mine prospection technology and exploration method. Succeeding resources prospection work of crisis mine is a practical job. It usually gets a good effect through exploring experiments of prospection technology and exploration method.This paper introduces pointedly to suitable exploration methods for Lala copper mine which include engineering revealed method on the techniques of pit and drilling, analogy method on the guidance of geologic theory, high-precision magnetic method, sound controlled electromagnetic method and primary halo analytical method. This paper verifies the geological abnormality of physic and chemistry with the geologic theory analysis mutually and gets some effective progress on the theoretical knowledge and prospectionpractice which has some reference on the next development.Through exploring mines and concluding of typical succeeding resources prospection work, the author has some new knowledge and new discoveryon typical deposit feature, and confirms the key indicator for ore prospection under the background that the genesis of mineral deposit has a loud dispute. Through expanding new ideas, the prospection scale of succeeding resources has increased.Considerable succeeding resources have been found in and around Lala copper mine through using the comprehensive prospection method, and it solves the mine crisis to a certain extent. On the basis of comparative study on different exploring achievement systems, the author finds an optimal combination for exploring ambient succeeding resources which is analogy of geologic feature + geologic chemistry(primary halo) + geologic physic(high-precision magnetic method and sound controlled electromagnetic method). This synthesized prospection model provides some scientific basis on the further ore exploration.
