Embodiment 1

[0055] The specific workflow in this implementation is:

[0056] Connect the adaptive dynamic hole sealer 2 and send it into the borehole, connect the grout outlet 15 of the automatic batching and grouting device 1 with the first grouting pipe 20-1, and connect the water supply pipeline 14-3 to the mine’s water supply On the line, energize the system.

[0057] At the beginning of grouting, the third pressure sensor 15-1 detects that there is no pressure in the self-adaptive dynamic sealer in the borehole, and the grouting operation needs to be carried out, and the hydraulic pressure sensor 10-2 detects that there is not enough grout in the tank, and the grouting operation needs to be carried out. Slurry replenishment, therefore by opening the first solenoid valve 13-2 and the second solenoid valve 14-2 to perform the replenishment and water replenishment operations, and through the second pressure sensor 13-1 and the electromagnetic flowmeter 14-1 to judge the amount of raw ma...

Abstract

The invention discloses a full-automatic dynamic hole sealing system. The full-automatic dynamic hole sealing system involves a plurality of execution units and a control unit used for controlling theexecution units, wherein each execution unit comprises a self-adaptive dynamic hole packer and an automatic proportioning and slurry supplementing device, the control unit is a central controller, each self-adaptive dynamic hole packer comprises a front hole sealing capsule, a middle connecting section and a rear hole sealing capsule, and each automatic proportioning and slurry supplementing device comprises a tank body, a stirring device, a material supplementing device, a water adding device, a pressurizing device, pressure sensors and a plurality of electromagnetic valves; the pressure sensors are located inside the material supplementing devices, the tank bodies and grouting pipelines of the self-adaptive hole packers correspondingly; the sensors are connected to the input end of thecentral controller; and each valve and the control ends of the devices are connected to the output end of the central controller, and the central controller is used for receiving signals fed back by the various types of sensors and outputting control instructions to control opening and closing of electromagnetic valves and device operation. The full-automatic dynamic hole sealing system has the advantages of being high in automation degree, high in control precision, high in stability and high in safety.

Description

technical field [0001] The invention belongs to the field of mine gas prevention and control, and in particular relates to a fully automatic dynamic hole sealing system. Background technique [0002] Gas disaster is one of the main disasters that affect the safe production of coal mines at present, and the most commonly used method in the management of gas disasters is drainage. Whether it is the pre-drainage of the coal seam, the drilling through the seam, or the high-level drilling Borehole sealing is required for all other means, and the effect of borehole sealing will directly affect the efficiency of gas drainage. Therefore, improving the quality of borehole sealing is of great significance to the control of gas disasters. [0003] At present, one-time sealing method is often used for drilling hole sealing in my country. Therefore, after the sealing is completed, if the drilling hole is affected by mining disturbance or stress appearance, and the hole breaks or cracks d...
