Abstract

Abstract

This paper aims at quality and parameters of rock mass in the No. 3 zone of Jing-chuan Mines. Statistics and numerical value models are applied to analyze the characteristics of classification and mechanical parameters based on the data of eleven drillhole logs. At first, the logging data were statistically analyzed. Joint and fissures at different depths in each drillhole were then analyzed. The rock masses were classified. The data for the mechanical model were obtained. And then, the three-dimensional mechanical model was made up which could taken into account characteristics of the entile rock mass. The mechanical characteristics of the distribution and change of mine mass were described. Finally, some important conclusions were summarized. The findings in the paper can provide practice data for the design of mining and numerical simulation.
