固胶比是树脂锚固剂制作时重要的指标，决定树脂锚固剂性能的优劣。针对树脂锚固剂在工程上的广泛应用，发现树脂锚固剂中树脂胶泥与固化剂配比对其工作性能存在重要的影响。为得到不同类型矿用树脂锚固剂的最佳固胶比，提升其工作性能，基于树脂锚固剂固化反应机理，采用数值模拟、实验室实验以及现场工程试验相结合的方法，研究了不同类型不同固胶比树脂锚固剂的锚固性能，得到了不同类型树脂锚固剂最佳固胶比例关系。结果表明：中速树脂锚固剂固胶比为2%(对照组)，4%,6%,8%和10%时，锚固工作时在锚杆横肋、锚固剂与锚杆横肋下表面接触区域均出现了不同程度的应力集中，应力峰值均在该区域；与对照组相比，随着固胶比逐渐增大，锚杆应力以及锚固剂剪应力峰值也逐渐的增大，且在固胶比为8%时两者应力值峰值达到最大。同理，对煤矿常用的超快、快速、中速3种树脂锚固剂依次进行固胶比与锚固力关系实验室实验，发现中速树脂锚固剂在固胶比为8%时锚固力峰值平均值最大，与对照组相比，其锚固力提升了23.70%；超快、快速树脂锚固剂在固胶比分别为8%,4%时锚固力峰值平均值最大，与对照组相比，锚固力分别提升了39.24%,7.35%。在煤矿巷道进行不同类型及固胶比的锚固实验得出，超快、快速、中速3种不同类型树脂锚固剂最佳固胶比分别为8%,4%,8%，为树脂锚固剂的配制以及选择提供了参考依据。

The catalyst-resin mastic ratio is an important indicator when the resin grout is made, and determines the performance of the resin grout. In view of the wide application of resin grout in engineering, it is found that catalyst-resin mastic ratio has an important influence on its working performance. In order to obtain the best catalyst-resin mastic ratio of different types of resin grouts for mines and improve their working performance, the paper is based on the curing reaction mechanism of resin grouts, using a combination of numerical simulation, laboratory experiments and field tests to study different types, the anchoring performance of the resin grout with different catalyst-resin mastic ratios has obtained the best catalyst-resin mastic ratio relationship of different types of resin grouts. The results show that when the medium-speed resin grout catalyst-resin mastic ratio is 2% (control group), 4%, 6%, 8% and 10%, the anchoring work is on the anchor cross rib, resin grout and the lower surface of the anchor cross rib. The contact area has different degrees of stress concentration, and the peak stress is in this area. Compared with the control group, as the catalyst-resin mastic ratio gradually increases, the bolt stress and the resin grout shear stress peak also gradually increase, and when the catalyst-resin mastic ratio is 8%, the peak stress value of the two reaches the maximum. In the same way, the three resin grouts commonly used in coal mines: ultrafast, fast, and medium speed, are successively carried out in the laboratory experiment on the relationship between the catalyst-resin mastic ratio and the anchoring force. It is found that the average peak anchoring force of the medium-speed resin grout is 8%. Compared with the control group, the anchoring force has increased by 23.70%; the ultrafast and fast resin grout has the largest average value of the anchoring force when the catalyst-resin mastic ratio is 8% and 4%, respectively. Compared with the control group, the anchoring force is the largest. Comparing with the control group, the anchoring force increased by 39.24% and 7.35%, respectively. Carrying out different types of anchoring experiments in coal mine roadways with different types and catalyst-resin mastic ratios, it is found that the best catalyst-resin mastic ratios of three different types of resin grouts for ultrafast, fast and medium speed are 8%, 4%, and 8% respectively, which provides a reference for the preparation and selection of resin grout.
