Description
Technical Field
The invention discloses a preparation method of a fast-setting soft rock grouting material, and belongs to the technical field of grouting materials.
Background
The total length of newly excavated tunnels of coal mines in China is up to 8000km every year, and most of the newly excavated tunnels are coal tunnels excavated in coal seams. The coal mining depth of China is increased at the speed of 8-12 m/year, the maximum depth reaches more than 1300 meters, and after 20 years, 1500m deep mining is carried out on many coal mines in China. Deep mining can cause the effects of high ground temperature, high water pressure, high earth pressure, and strong mining dynamic pressure. As the depth of coal mining increases, it is inevitable to face more and more soft rock problems, subject to geological conditions. According to investigation, the working face production stop time accounts for about 50% of the total production stop time due to the roof fall of the soft surrounding rock coal face, and about 20% of the coal faces in China are in a low-yield state due to the unsatisfactory roof control state every year. More and more roadways are arranged in the coal seam, surrounding rock pressure is increased, the control difficulty of the surrounding rock of the roadways is increased, and deformation and instability of the roadways become important problems restricting safe and efficient production of mines. The roadway is developed in the soft rock, because the deformation enables the roadway surrounding rock to release a large amount of energy, the weak surface of the surrounding rock is further developed, meanwhile, the surrounding rock expands, loosens, deforms and crushes to generate new cracks, the range of the loosening zone of the roadway surrounding rock is enlarged, and the properties of the surrounding rock in the crushing zone are greatly different from those before crushing. For a soft surrounding rock mining roadway, the deformation of the surrounding rock is large, and in order to improve the maintenance condition of the roadway, two effective modes can be adopted. On one hand, the structure and the performance of surrounding rock masses are improved, the pressure bearing capacity of the rock masses around the roadway is improved, and the potential self-bearing capacity of the surrounding rock is fully exerted; on the other hand, the mutual relation between the surrounding rock and the support needs to be researched, and the surrounding rock can be effectively maintained by adopting reasonable support measures.
The instability of the soft rock roadway of the coal mine affects the progress and quality of mining engineering, increases the labor risk of workers, brings dangerous factors and serious persons to the coal mine production, and even causes great loss of life and property. The hydrogeology condition of the coal field in China is complex, and a lot of coal reserves to be mined are threatened by more serious soft surrounding rocks, so that the method has very important practical significance for preventing and treating the soft surrounding rocks. Meanwhile, as more and more coal mines enter deep mining, the problems of supporting technology of coal mine soft rock roadways and the like face more challenges due to the fact that deep rocks have high stress, high temperature and more soft rocks with serious rheological phenomena. However, grouting support is one of the important methods for supporting the soft rock roadway of the mine, and proper grouting support has the obvious advantages of reducing the burden of the mine support, reducing the cost per ton of coal, improving the working efficiency and quality, reinforcing the weak section of the roadway, reducing the water inrush probability and prolonging the service life of the mine. However, the existing soft rock is soft and broken, has poor engineering property, is easy to expand by absorbing water, and affects the reinforcing effect, so that the research on the grouting material which has the characteristics of strong injection capability, short condensation time, high strength of a stone body and good impermeability and can not cause the water absorption expansion deformation of the soft rock to affect the reinforcing effect is necessary.
