Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mining, more particularly, it relates to a coal mine grouting process parameter intelligent monitoring sensor device. BACKGROUND

[0002] Coal grouting is to solve various safety and environmental problems encountered in the process of coal mining. In coal mining, the roof of the coal seam and the surrounding rock of the roadway may be broken, grouting can enhance its strength and stability, prevent roof fall, collapse and other accidents, in complex geological structure areas such as faults and folds, grouting can enhance the integrity of the surrounding rock and reduce the risk of geological disasters. Coal grouting is an important technical measure to ensure the safety of coal production, prevent disasters, protect the environment and improve resource utilization efficiency. The grouting sensor is a device specially used to measure and monitor the pressure in the grouting process, widely used in civil engineering, coal mines, tunnel construction and other fields. The grouting sensor usually uses high-precision resistance strain gauge as a pressure sensing chip, and through the design of specially treated diaphragm and mechanical transmission structure, it can accurately measure the pressure in harsh environments.

[0003] The grouting sensor, as the core component of the entire grouting system state feedback, plays a good guiding role in monitoring and evaluating the entire grouting process.
