| 摘 要： | 为了保持硐室的稳定性,确保硐室能够安全、正常使用,必须采用经济、合理的支护方式.基于围岩松动圈范围的大小及其空间分布规律对选择硐室支护方式的重要性,利用高密度电阻率法勘探的原理并结合地下硐室开挖与支护的施工特点,提出了利用锚杆钻机钻孔、锚固剂封闭孔口、压力容器灌注水泥浆、高密度电阻率法采集数据的松动圈测试技术,研究了硐室开挖与支护后其围岩的变形程度与导电性的关系.将该技术应用于淮北矿业集团刘店煤矿副井马头门巷道松动圈的测试中.结果表明:处于弹性变形状态的围岩,其导电性会一定程度地增强(即电阻率减小);处于塑性变形状态的围岩,其导电性会显著地减弱(即电阻率增大).

| Abstract: | In order to keep the stability of a chamber and to ensure a safely and normal application of the chamber, an economic and rational support pattern must be adopted.Due to the size of the strata released zone and the three-dimensional distribution law are important to select the support pattern of the chamber and with the exploration principle of high density resitivity method and the construction features of excavation and support for the chambers,the paper provided the measurement and test technology of the... |
