摘　　要：我国煤矿顶板事故死亡人数约占煤矿总死亡人数的40%,其中80%的顶板事故发生在回采工作面。当岩层离层和断裂等破坏状态及过程(包括裂断时间和位置)的信息被监测到后,就可以对顶板进行垮落的预报,并实施针对性的控制措施,从而避免顸板事故发生。将支架工作阻力监测系统、顶板离层监测系统、锚杆应力监测系统、钻孔应力监测系统等现有的系统进行集成,并实时显示各种应力和位移的变化,可以实现顸板的动态监测,为煤矿的安全高效生产奠定良好的基础。The death ratio of the roof accidents is about 40% of all deaths in China collieries. About 80% of the roof accidents occur on the working face. When the information such as the abscission and breaking state （including the breaking, time and location）of the terrane are monitored arid acquired, the tool collapse can be forecasted and then the relevant control measures to avoid the roof accidents implemented. To integrate the existing systems for monitoring the support working resistance, the roof abscission layer, the bolt stress, drilling stress and so on, so as to real-time display all kinds of stress and displacement alternation, thus the dynamic monitoring for each roof can be realized, which provides a strong foutidation 9%r the colleriry production with safety and high efficiency.
