The excavation of an ultra-deep mining shaft in Huize Lead and Zinc Mine of Yunnan Province has encountered some engineering challenges because of the high geostress and high penetrating hydraulic pressure of the surrounding rock at depth.To determine the support scheme with the best steel fiber reinforced concrete proportion for this deep shaft wall,10 kinds of concrete specimens with different steel fiber admixtures were made from sand,stone,cement,and other materials from the mine site,and uniaxial compression,splitting tensile and four-point bending tests were carried out after 14 d standard curing.Based on the strength test results of steel fiber reinforced concrete and on-site working conditions,8 evaluation indexes such as tensile strength and labor cost are selected as the discriminant indexes of the model,and the extension analytic hierarchy process and the improved entropy weight method are respectively selected to weight the evaluation indexes,a comprehensive evaluation model is constructed based on game theoretical portfolio assignment.The evaluation model was used to calculate the relative fitting degree of 10 SFRC lining support schemes,and Scheme T2-30 (long fiber content 40 kg/m3,medium long fiber content 5 kg/m3,short fiber content 10 kg/m3)SFRC lining support was selected to be the final optimum scheme for the ultra-deep shaft wall support.The field application shows that the SFRC lining support has a good supporting effect on the deep shaft wall,and the control effect on the integrity of the shaft wall and the stability of the shaft is obviously better than the previous single-mixed steel fiber reinforced concrete support scheme.
