Abstract
The invention relates to an auxiliary device for testing the mechanical property of a filling material, which is suitable for testing the mechanical property of comprehensive mechanical solid filling coal mining materials for coal mines and metal mines. The auxiliary device comprises a base and a steel barrel which is arranged on the base, wherein a piston and a hollow transfer lever which is connected with the piston are arranged in the steel barrel, the steel barrel is connected with the base through a flange, two sides of the upper part of the steel barrel are symmetrically provided with two handhold handles, the piston is matched with the steel barrel in a sliding manner, and the center of the upper end surface of the piston is provided with an annular groove which is fixedly connected with the hollow transfer lever. The mechanical property of different granular materials under different pressure situations can be tested by applying the pressure on the filling materials, and theoretical evidence can be provided for controlling the rock movement and surface subsidence after the cut and fill mining. The auxiliary device is simple in structure, safe, efficient, less in investment, convenient to operate and wide in practicability.
Description
Technical field
The present invention relates to a kind of compaction material mechanical property testing servicing unit, be particularly useful for the Mechanics Performance Testing to colliery and metal mine comprehensive mechanization solid filling coal mining material.
Background technology
Along with China is with spoil, flyash, loess, the solid materials such as building waste are the maturation day by day of the comprehensive mechanization solid material filling coal mining technology of compaction material, realized gradually the scale exploitation of " three times " being pressed to coal and metal mine, and realized the effective filling to goaf, effectively raise the rate of extraction of coal resources, solve China's " three times " and pressed coal mining problem, solved discarded object spoil simultaneously, flyash, the ground stacking problem of metal tailings, comprehensive mechanization solid material filling coal mining technology has important practical significance and wide application prospect.And compaction material is as the requisite part of filling coal mining, the test of its mechanical characteristic is contributed to grasp more clearly to the physical and mechanical property of compaction material, for strata movement after filling mining and subsidence, control theoretical direction is provided.
Summary of the invention
