摘要
工作面事故统计表明,矿区工作面的事故主要由端面顶板冒顶、煤体片帮事故和机械故障事故等组成,工作面初次来压和周期来压期间发生频率较高。结合矿区实际地质条件和发生事故的特点,了解和掌握本矿工作面的矿压显现规律,最终评价支架-围岩的适应关系,确定支架-围岩控制参数,从而在前期保证工作面安全生产,保证人员和设备的安全。
The accident statistics of the working face show that the accidents of the working face in the mining area are mainly composed of the roof falling of the end face,the coal body spalling accident and the mechanical failure accident.The frequency of the first pressure coming from the working face and the periodic pressure coming from the working face is relatively high.According to the actual geological conditions of the mining area and the characteristics of accidents,this paper tries to interpret the law of mine pressure appearance in the working face of the mine,evaluate the adaptive relationship between the support and the surrounding rock,and determine the control parameters of the support and the surrounding rock,so as to ensure the safe production of the working face and the safety of personnel and equipment in the early stage.
