摘要:
为了研究地下巷道在爆破振动作用下的响应特征，以某露天铁矿转地下爆破开挖为研究背景，在地下巷道确定监测位置，结合爆破振动理论建立爆破振动衰减数学模型。为弥补试验方案不足，利用FLAC 3D软件建立地下巷道概念模型，分析地下巷道在爆破振动作用下的速度、位移的变化特征，并与现场试验进行对比。结果表明：当爆心距小于50 m时，水平径向峰值振动速度衰减变化率达到53.63%，而水平切向、竖直方向峰值振动速度衰减变化率分别达到53.07%和47.02%。通过对爆破时地下巷道的数值模拟分析可知，爆破振动速度变化主要集中在巷道的顶板及底板，而巷道竖直位移呈现先逐渐变大、后趋于平稳的状态，处于巷道安全允许范围之内。
Abstract:
In order to study the response characteristics of underground roadway under blasting vibration, a mathematical model of blasting vibration attenuation was established based on the theory of blasting vibration and the monitoring position of underground roadway in an open pit mine under the background of underground blasting excavation. In order to make up for the deficiency of the test scheme, a conceptual model of underground roadway was established by FLAC 3D software. Variation characteristics of velocity and displacement of underground roadway under blasting vibration were analyzed, and they were compared with those obtained from the field test. The results show that when the distance between detonation centers is less than 50 m, the attenuation rate of peak horizontal and radial vibration velocities reaches 53.63%, while the attenuation rate of peak horizontal and vertical vibration velocities reaches 53.07% and 47.02%. Through the numerical simulation analysis of underground roadway, the change of blasting vibration speed mainly concentrates on the roof and floor of the roadway, while the vertical displacement of the roadway shows a state of gradual increase and then becoming stable, which is within the safe allowable range of the roadway.
