Abstract

The invention relates to a method and device for continuously measuring the properties of a reactive polymer material used in coal mines and a coal-rock mixture after grouting. After the coal (rock) body is plastically deformed by loading, the reactive polymer material slurry is injected into the coal (rock) In the central hole of the sample, simulate the flow of the reactive polymer material slurry in the secondary cracks of the coal (rock) body, and test the coal (rock) after injecting the polymer material through the temperature measurement port set on the insulation cylinder. ) body temperature changes, providing a reliable technical means for the feasibility analysis of the safe application of mine-used reactive polymer materials; by measuring the permeability coefficient of the coal (rock) body after injecting reactive polymer materials, characterizing the injected reactive polymer materials The application effect of the material on the water plugging operation of coal (rock) mass; through the comparative test of the uniaxial compressive strength of the coal (rock) mass before and after the injection of the reactive polymer material, it is reflected that the plastic deformation of the coal (rock) before and after the injection of the reactive polymer material is (rock) reinforcement effect.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and relates to a method and a device for continuously measuring the characteristics of a mine-used reactive polymer material and a coal-rock mixture after grouting. Background technique [0002] The efficient, clean and low-carbon utilization of coal is the top priority of society, and related technologies are developing in a favorable direction. Vigorously promoting the clean utilization of coal will help promote the revolution of social energy production and consumption. But at the same time, due to the complex geological conditions of the underground coal seams in coal mines, many coal seam mining mines adopt the "downward" mining method, aiming to reduce the pressure and increase permeability of the underlying coal seam through the mining of coal seams. Threat degree of coal seam gas disaster. However, during the development and mining of the underlying coal seam, due to the mining...
