| 摘 要： | 结合城郊煤矿11201工作面运输巷顶板淋水情况下锚杆锚固力现场测试结果，自行设计了实验装置，研究了钻孔淋水对树脂锚杆锚固力的影响、在现场测试中，当钻孔的淋水量小于128mL／min时，树脂锚杆的锚固力保持不变；当淋水量大于583mL／min时，树脂锚杆的锚固力比无淋水时的锚固力下降35％以上．沿巷道轴向布置卸水孔，采用集中排放，同时加大锚杆支护的密度可以改善顶板淋水时锚杆支护的效果．

| Abstract: | According to the spot experiment result of bolt anchor-hold in the condition of draining water in the roof on haulage roadway, 11201 coalface, Chengjiao coalmine, the test facility was designed independently and the influence of the anchor-hold of the resin bolt by the draining water in the drill hole was studied.In the spot test, as the draining water content around the drill hole is less than 128 mL/min, the anchor-hold can keep constant; as the content is more than 583 mL/min, the anchor-hold fall down above 35% than the content is zero.Such ways can improvement the rock bolt supporting effect by the draining water in the drill hole, which are to layout relief water holes, adapt centralized discharge, and exaggerate the density scale of the bolt support. |
