Study on the Wall Rock's Physical and Mechanical Parameters of Testing Stope in No.10-6 Ore Body of Yunnan Tin Mine

Qiu Jingping1 Xing Jun1 Sun Xiaogang1 Song Zhanping2(1 Northeastern University; 2 Xi'an University of Architecture & Technology)  
The physical parameters and mechanical parameters of rock (body) are characterized by randomness and variability. The current research on rock's parameters is made mainly through laboratory experiments and experience. Based on a great deal of lab tests and the analysis of the probability distribution law of engineering rock (body), the statistics characteristics of the physical and mechanical parameters of marble in the testing stope of No. 10-6 ore body in Yunan Tin Mine were studied. The results show that these parameters of marble are random and variable, and their testing data have evident statistic regularity. Therefore, the probability distribution law of each parameter can be used to rationally determine the physical parameters and mechanical parameters of the rock (body) in the testing stope, so as to provide a basis for determining a rational mining mode for the ore body.
