在对近地表厚硬关键层运动引起地面震动案例分析的基础上,综合厚硬关键层破断及能量传播规律,提出了“震动损害边界”的观点,并以质点震动速度作为震动损害的主要评价指标,初步建立了矿震诱发地面震动损害的评估方法.根据厚硬关键层破断诱发强矿震的基本条件,提出了矿震引起地面震动损害的防控思路:1)改变矿震孕育的条件;2)减小一次矿震释放的能量.通过某矿16101工作面开采实践,取得了良好的效果.
Based on the case analysis of surface ground motion induced by thick and hard key ground near the surface, the view of “damage boundary” is proposed based on the fracture of thick and hard key layers and the energy propagation law, and the vibration velocity of particle is taken as the vibration damage The main evaluation indexes are as follows: Firstly, the assessment method of ground vibration damage induced by mine shocks is preliminarily established.According to the basic conditions of induced strong earthquake of thick and hard key stratum, the prevention and control mentality of ground vibration damage caused by mine earthquake is proposed: 1) Of the conditions; 2) to reduce the energy of a mine shock release through a mine 16101 mining practice, and achieved good results.
