Problems solved by technology

[0002] In the construction and production process of coal mines, the flow trajectory of fault water is constantly changing due to the continuous forward mining of coal seams. Therefore, it is necessary to dynamically monitor the flow trajectory of fault water in coal mines. Buried underground, it needs to be mechanically excavated to the coal seam area to excavate coal. When the excavation equipment passes through the water-rich fault, due to the continuous forward mining of the mining face, the vibration causes the fault of the mining face to change. Rapid monitoring of hydrology, so it is necessary to install monitoring equipment on mining equipment (such as figure 1 shown) for real-time dynamic monitoring, but when the existing equipment is used for monitoring, the vibration generated during the mining process of the equipment will cause the fault water to slosh, and at the same time cause cracks inside the rock mass, resulting in changes in the flow direction of the fault water, and the water in the The amount of transmission in cracks is small, so that the existing monitoring equipment cannot dynamically monitor the flow path of fault water in real time and accurately, and may not be able to predict the occurrence of rock mass side collapse accidents, which poses a threat to the safe operation of monitoring equipment. For this reason, we propose a coal mine hydrological dynamic monitoring system to dynamically monitor the hydrological conditions of the large faults in the roadway during the mining process, and to protect the monitoring equipment in the event of dangerous accidents

Abstract

The invention discloses a coal mine hydrological dynamic monitoring system which comprises graphite powder used for enhancing the conductivity of fault water, an injection anchor rod used for injecting the graphite powder into a large water-rich fault and a fixing plate installed on the back side of tunneling equipment, and a damping sliding rail is installed on the side, away from the tunneling equipment, of the fixing plate. A monitoring mechanism is slidably connected to the surface of the damping sliding rail, and an arc-shaped sliding groove is formed in the surface of the fixing plate. A coal mine hydrological dynamic monitoring system is characterized in that a rotary spray head and a rotary nozzle uniformly spray graphite powder into a water-rich fault to increase the conductivity of water in the fault, so that a detection signal of a minor fault generated by mining can be increased, and the hydrological condition of the minor fault generated in the mining process can be quickly mastered to perform quick early warning and protection; and meanwhile, two layers of protection are provided for the whole sliding table, so that the detection equipment is prevented from being damaged by sudden water permeation accidents, and relatively good practicability and safety are achieved.

Description

technical field [0001] The invention relates to the field of coal mine hydrology monitoring, in particular to a coal mine hydrology dynamic monitoring system. Background technique [0002] In the construction and production process of coal mines, the flow trajectory of fault water is constantly changing due to the continuous forward mining of coal seams. Therefore, it is necessary to dynamically monitor the flow trajectory of fault water in coal mines. During coal mining, coal seams are often deep. Buried underground, it needs to be excavated to the coal seam area to dig coal. When the excavation equipment passes through the water-rich fault, due to the continuous forward mining of the mining face, the vibration of the mining face causes the fault of the mining face to change. Rapid monitoring of hydrology, so it is necessary to install monitoring equipment on mining equipment (such as figure 1 As shown) for real-time dynamic monitoring, while the existing equipment is moni...
