Research Of Rock Pressure And Support Technology Of Deep Mine Exploiting

With the development of mine exploit in our country, it is true that the depth of mining must have been increased, and it also effects the mining now and the mine building in the future. How to face to the complicated geological conditions and to solve the technological problems of deep mining. It will be very important to safe and economic and appropriate for deep mining in long-term. In this paper, the advanced research techniques in oversea is borrowed, combined measurement of ground stress in job site and the data processing of tunnel mine pressure,used the method of rock stress state analytical system . Example for Hongyang Third Mine, such as the stress distribution of rock mass of deep mining area in Hongyang Third Mine , and supporting and damage way of the tunnels, and activity law of surrounding rock , and the law of ground pressure , and the supporting way and supporting parameter in deep-mining, all of them are determined. That bolting or combined support way is good for this kind of tunnels is determined. The appropriate support system is designed, it is good for the practical application in Hongyang Third Mine, and it is also good for other deep-mining areas in our country.
