Test and Analysis of Expansion Characteristic of the Waste Filling

摘要：

Under three mining (under the buildings, under the railway and water) coal problem has become one of the growing problems in the coal mining and filling mining technology, because of its controlling the strata movement and limiting the role of surface subsidence.Selecting waste rock as filling material, not only mine under three coal, control surface deformation, but also to make full use of waste resources, conducive to environmental protection. Filled waste rock is full of rock broken, has a general rock breaking under pressure and expansion of deformation characteristics of master broken waste rock crushing and expansion, for further study on deformation characteristics of compaction of the waste, discussion on the waste rock filling of bulk density variation in the process to provide the necessary theoretical basis.
