Experimental on Performance Optimization of High-Strength Inorganic Anchoring Materials for Mining
The high prestressed anchor cable support of the roadway floor is one of the effective methods to solve the floor heave of the roadway.However,since the bottom plateand and the bottom of the anchoring hole usually contain water,the anchoring effect of resin anchoring agent and cement mortar anchoring agent is poor during the bottom plate the anchoring force is low,and the fixed force decay is fast.Therefore,based on the self-developed anchoring raw materials,the influences of silica fume,mineral powder,metakaolin and polypropylene cellulose on the properties of anchoring materials are studied by orthogonal test,and through SPSS data analysis software,the test results are analyzed for variance,range,and Duncan multiple comparisons.Results show that when the water-cement ratio is 0.4,and the additive amount of silica fume,mineral powder,metakaolin and polypropylene cellulose accounts for 1.50％,0.10％,12.00％and 0.05％of the total amount of anchoring raw materials,respectively.The compressive strength of anchoring material solidified body is stronger.
