穿层巷道分段支护技术研究
|
摘要
以阳煤一矿S8208高位抽采巷为工程背景,采用了工程类比、数值模拟和工程实践等方法进行研究,获得了不同围岩的岩性组成类型,并通过模拟得出了细砂岩-泥岩组合区域到砂质泥岩-煤-泥岩组合区域为支护重点,通过设置分段支护与普通支护的对比,证明了对穿层巷道采用分段的方式进行支护的合理性,提出了支护方案,并通过矿压监测对方案进行了验证,该支护能够有效控制穿层巷道围岩。
S8208 high-level drainage roadway of Yangmei No. 1 Mine was taken as the engineering background,engineering analogy, numerical simulation and engineering practice were used to study the lithologic composition types of different surrounding rocks by simulation. The sandstone-mudstone combination area to the sandy mudstone-coal-mudstone combination area wa the key point of support. By comparing the sectional support with the common support, the rationality of supporting the through-roadway by segmentation was proved. The support scheme was proposed and the scheme was verified by mine pressure monitoring, with good support effect.
