全断面短锚索间排距支护效果的数值模拟

针对鹤壁集团六矿2145底抽巷产生明显变形，并有进一步恶化的趋势，采用FLAC3D数值模拟软件对全断面短锚索间排距支护效果进行了模拟分析，根据模拟结果，结合实际施工情况及经济效益分析，选择间排距为1.4 m的锚索支护，可以满足生产需要，且锚索受力稳定，很好地控制了围岩的变形，确保了巷道的稳定性。

Numerical Simulation Research on Supporting effect of Row Spacing Between Short Anchor Cable of Whole Section

The deformation of the end of the drainage of Heibei Group six mine 2145 is obvious,and the deformation is becoming bigger and bigger. Therefore,to deal with this situation,some relative research work is conducted,that is the numerical simulation research on supporting effect of row spacing between short anchor cable of whole section based on FLAC3D software.Combining the numerical simulation results with the actual construction condition and economic benefit analysis, the row spacing of anchor cable is determined to be 1.4 meters so as to meet the production needs. The research results indicated that, the force of the anchor cable is stable,the deformation of surrounding rock is controlled effectively, at the same time the stability of the roadway is ensured.
