Problems solved by technology

So far, there are few related studies on the sensitivity analysis of the micro-parameters of the cemented filling body on the mechanical response, so the primary and secondary relationship of the micro-parameters cannot be well determined. When the method is complex and inefficient
Moreover, in the prior art, the prediction of the mechanical response characteristics of the cemented backfill is mostly based on the experimental test method, which has a long test period, low efficiency, and high manpower and material resources, which affects the rapid promotion and application of the new cemented backfill, and is likely to cause mining problems. Delay in construction period

Description

technical field [0001] The invention relates to the technical field of cemented filling mining, in particular to a method for predicting the mechanical response characteristics of a cemented filling body based on sensitive microscopic parameters. Background technique [0002] With the development of national science and technology, the requirements for energy saving and environmental protection technology are getting higher and higher. Traditional cemented backfill mining uses cement as the cementitious material, and the cost of cement is as high as 75% of the total backfill cost. Through research and development, tailings contain active silica and alumina, and using tailings instead of part of cement as cementing material can not only reduce the discharge of tailings, effectively reduce the cost of filling mining, but also improve the strength of the filling body and reduce the ground The collapsed area also plays an active role in promoting the protection of the environmen...
