| More and more Gypsum and other nonmetal natural resources have been demanded along with the development of national economy, the gypsum yield grows roughly by10%in our country. Taochang Gypsum Mine belongs to super-huge type gypsum mine inland in Hanshan county Anhui province, which has high quality gypsum and468.60m ore body controlling of thickness on the average, ranging from347.27m and562.35m.A stratum of limestone about100m thick carpeted with the upper of the orebody, which corrosion is obviously, appearing evaporite solution breccia and soon become honeycomb structure after corroding. Although there have rock pillar of more than100m high remaining in the mine production, once water-transmissible fault be caught in mining process vital disaster would be taken palace as this stratum corroded limestone has well structure. It has very important significance to mine safety in production to tidy, statistics, analysis structure data in mine construction and manufacture period. So analysing mine structure feature and controlling the space spread of boundary fault by combining observational data and leaving water-proof pillar reasonable on the base of researching aquifer hydrogeology feature.This paper also present CSAMT which arouse underground rock by artificial source of field to receive once field potential shaping from different supply frequency. As the different frequency field spread different deepness in the stratum that both of them make up mathematical relation, rock with different conductivity generated different potential and magnetic field when current flowing past. CSAMT is an electromagnet exploration method of using the different conductivity to observe once field potential and magnetic field intensity transformation. |
