针对目前回采工作面预防与治理煤壁片帮工作的滞后性、盲目性等特点,建立回采工作面煤壁片帮预测体系,通过应用层次分析法和模糊数学的基本原理对煤壁的稳定性进行评判,并为保持煤壁稳定性而采取的控制措施提供依据。
Aiming at the characteristics of lagging and blindness of prevention and control of coal wall slab work in the mining face at present, the coal wall slab prediction system of coal mining face is established. The stability of coal wall is analyzed by applying the analytic hierarchy process and the basic principle of fuzzy mathematics To judge and provide the basis for the control measures taken to maintain the stability of the coal wall.
