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.

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
