%X Based on the study of ground pressure in mining face and roadway through experiments in site and model testing in lab,the behaviors of ground pressure are compared for the pitching oblique underhand mining and straight long-wall mining. The reasons of uneven ground pressure are obtained for pitched oblique underhand mining. Meanwhile,the adaptable parameters in mining face of pitching oblique underhand mining are discussed,and they could be used for the control of ground pressure and optimum design.
