Abstract

The invention discloses an intelligent and dynamic monitoring system for mine grouting and a working method thereof. The system comprises grouting pipes, a ball valve, a grout recovery pump, a high-precision intrinsic safety type pressure sensor, a high-precision intrinsic safety type flow sensor, a grouting anchor rod positioning system, a grouting anchor rod, a stirring device, a mining area grout pump station, a data transmission system, a ground data acquisition system and a coal mine dispatching center, wherein a plurality of grouting connectors are arranged on the periphery of the miningarea grout pump station, and the grouting pipes are arranged on the sides, deviating from the mining area grout pump station, of the grouting connectors separately. Through interaction of the ball valve, the high-precision intrinsic safety type pressure sensor, the high-precision intrinsic safety type flow sensor, the grouting anchor rod positioning system, the grouting anchor rod and a ground data acquisition system, grouting parameters are accurately collected in the grouting process, the grouting effect is detected in real time, and the grouting anchor rod which does not reach the standardcan be timely repaired.

Description

technical field

[0001] The invention relates to the technical field of mine grouting, in particular to an intelligent and dynamic monitoring system for mine grouting. Background technique

[0002] With the increasing mining depth, the pressure on the surrounding rock of the roadway is also increasing, especially the weak and broken roadway support is very difficult. Conventional support methods cannot effectively control the surrounding rock of the roadway, which affects the roadway. security and stability. The grouting bolt combines anchoring support technology and grouting reinforcement technology, which greatly improves the strength and self-supporting capacity of the surrounding rock, can effectively control the weak surrounding rock, and keep the roadway stable. The grouting amount and the grouting pressure of the grouting anchor will directly affect the grouting effect during the grouting process, so the grouting pressure and grouting flow rate of each grouting anchor...
