| With deep mining development of coal resource, many safety problems have arisen and become serious gradually, such as laneway deformation, rock burst, and so on. Multi-source techniques and methods must be adopted to monitor and study behave law of mine pressure, thus safety and efficient production of mining can be guaranteed. It takes the working face No. VI 15-22020 and its transportation laneway of 2nd level of the 8th mine as the research subject. Borehole stress meter, multi-point extensometer, instrument of roadway convergence were used to monitor characteristics of abutment pressure of working face, roof displacement and section deformation of surrounding rock of laneway under the influence of mining. And behave law of mine pressure with deep mining in the 8th mine of Pingdingshan coal group is summarized and analyzed, which have important directive to mining design and safety. |
