Description

[0001] The present invention relates to the technical field of overburden rock separation grouting, and in particular to an overburden rock separation grouting process parameter detection terminal and an effect monitoring and evaluation method. Background Art

[0002] Overburden stratum grouting refers to a technology that injects slurry into the overburden stratum to fill and reinforce the stratum during coal mining or other underground projects, thereby controlling surface subsidence and protecting surface buildings and the environment. Overburden stratum grouting technology plays an important role in controlling surface subsidence, protecting surface buildings and the environment, and improving resource recovery rates. In the future, it will continue to develop in the direction of intelligence and environmental protection.

[0003] Grouting pressure is usually used to detect the parameters of the overburden separation grouting process. Grouting pressure is an important parameter that affects the diffusion and filling effect of the slurry. The grouting pressure is monitored in real time by a pressure sensor installed on the grouting equipment. However, this method has certain problems. When the density is uneven due to uneven stirring of the grouting tank, the overburden separation grouting has reached the standard, and there is a blockage in the transmission, the grouting pressure will increase, which is less practical.
