摘要:为确定合理的预掘巷道间岩柱尺寸,以某矿通过13.5 m大落差断层为工程背景,采用UDEC数值模拟方法,研究了不同预掘巷道间岩柱尺寸的岩柱内垂直应力、塑性区分布及预掘巷道顶底板移近量变化规律,得出合理的预掘巷道间岩柱尺寸为3 m,且其合理性在现场工程实践中得到了验证。
In order to determine the rational determination of rock pillar between two pre-driven roadways, crossing through 13.5 m throw fault is taken as engineering background. We adopt UDEC numerical simulation method to research the variation of vertical stress and plastic zone of rock pillar, and the roof and floor convergence of pre-driven roadway, the rational determination of rock pillar between two pre-driven roadways is 3 m, and its rationality is verified in the engineering practice.
