Abstract: In order to study the problems of mine pressure in Sikeshu Mining Area, stress-relieving measurement test were made with improved hollow inclusion stress meter at 3 measurement points in Sikeshu Mining Area. Based on the measured results, three-dimensional stress state of each point was computed by stress calculation program, and the relationship between in-situ stress and geological structure was analyzed with the geological structure factors of the mining area. The laws of in-situ stress distribution and the relationships between in-situ stress and geologic structure in Sikeshu Mining Area were obtained. The reasons for the strata behaviors are primarily analyzed.
