针对贵州煤矿准备生产阶段巷道实际采矿地质条件,为了有效控制准备巷道围岩的稳定,按照实际地质条件建立相似数字模型,分析垂直位移分布、最大不平衡力等特征,然后通过向巷道围岩植入锚杆,再分析以上参数,并运用矿山压力与岩层控制理论分析巷道围岩稳定性特征,为此类巷道围岩稳定性分析及围岩控制研究提供指导作用。
Preparation for the production phase of Guizhou coal mine roadway actual mining geological conditions, in order to effectively control the stability of surrounding rock to prepare, create similar digital model in accordance with the actual geological conditions, analysis the vertical displacement distribution, the maximum unbalanced force and other characteristics, and then implanted through the roadway bolt, and then analyze the above parameters, and the use of un- derground pressure and strata control theory to analyze surrounding rock stability characteristics, for such roadway surrounding rock stability analysis and control research guiding role.
