摘　　要：研究了MK-1高效增强剂在巷道锚喷支护中的应用，通过对混凝土作用机理和巷道支护的研究，得出了MK—1高效增强剂在巷道喷射混凝土过程中的作用及喷射方法。在实际巷道支护中，喷射混凝土加入增强剂后，其抗压强度提高40％～50％，回弹率降低到10％，达到同等强度时其成本每米可节省29-43元。This paper presents a study on the application of MK-1 highly effective fortifier in roadway bolting-shotcreting support. Through a study on the functioning mechanism of concrete and roadway support, the function of the MK-1 fortifier in the shotcreting process in roadway support as well as the shotcreting method is produced. In actual roadway support practice, once this fortifier is added to the shotcrete, the compression strength of the material will be increased by 40% - 50% while the rebounding ratio be reduced down to 10%. For the same support strength of the shotcrete, shotcrete cost can be reduced by 29 - 43 yuan/m^2.
