Preparation system of mine microorganism mineralized filling

Abstract

The invention discloses a preparation system of a mine microorganism mineralized filling material. The preparation system comprises a manual liquid taking and injecting system, an eight-channel mineralized liquid pouring system and a material soaking and maintaining system, all the systems are placed in a fume cupboard; the manual liquid taking and injecting system is used for accurately and quickly measuring, taking and injecting liquid; the eight-channel mineralization liquid filling system is used for efficiently pumping mineralization liquid and bacterium liquid of multiple test pieces; the material soaking and maintaining system is used for further enhancing the strength of the mine microorganism mineralized filling material. According to the invention, a plurality of mineralized material test pieces can be efficiently prepared at the same time, the material strength is further enhanced, and the mine environment temperature is simulated to a great extent, so that a new process isprovided for the preparation of a novel filling material, and the method is better used for preparing a microbial mineralized filling material in a mine; the theoretical basis of the preparation method of the novel mine filling material is enriched.

Description

technical field [0001] The invention belongs to the technical field of mine filling material experiments, and in particular relates to a preparation system for mine microbial mineralization filling materials. Background technique [0002] Coal mining produces a large amount of coal gangue solid waste accumulated on the surface, and the filling coal mining technology can make good use of the underground goaf space, and at the same time solve the large amount of coal gangue solid waste accumulated on the surface. The new filling material prepared by the method of microbial mineralization can fully support the aggregates in the filling material, fill the gap between the aggregates of the filling material, achieve a good supporting effect, and prevent the surface Subsidence, protection of surface ecology, etc. However, the existing methods for preparing downhole microbial mineralized filling materials are very inefficient, because only one specimen can be prepared by perfusion ...
