CHINA MINE ENGINEERING

In order to fully recover rich resources of Gongchangling underground mine and improve its economic benefits of production, it is necessary to update and optimize the existing mining methods. The study of physical-mechanical properties of ore is an important preliminary work in determining stope structural parameters and analyzing stope stability in the process of mine design. Based on earlier exploration results of the mine and lithology revealed in production practice, laboratory test on rock physical-mechanical property parameters were conducted on ore samples of 8 different lithology types from Gongchangling underground mine and plenty of parameters on rock physical-mechanical property have been obtained, which will provide basic data for later mining engineering design study.
