Abstract

The present application discloses a method for monitoring the working state of a hydraulic support safety valve, which relates to the technical field of coal mine safety mining. The pressure change data of the hydraulic support column and the working characteristics of the hydraulic support column safety valve determine the working state of the hydraulic support column safety valve in the coal mine working face. Through the technical solution of the present application, the real-time monitoring of the hydraulic support pressure of the coal mine working face can comprehensively obtain the change of the working resistance of the hydraulic support, and according to the working state of the safety valve, the opening pressure and length of the safety valve of the hydraulic support safety valve of the coal mine working face can be obtained, thereby To achieve the purpose of evaluating the working performance of the hydraulic support, the pressure state of the top plate, and whether the safety valve is damaged.

Description

technical field [0001] The present application relates to the technical field of coal mine safety mining, in particular to a method for monitoring the working state of a hydraulic support safety valve. Background technique [0002] The hydraulic support is the equipment that supports the top and bottom plates of the coal mining face in coal mine production. It is used to isolate the working face from the goaf and plays an important role in ensuring the safety of equipment and personnel in the mining face. The safety of the hydraulic support column The valve is the core component to protect the hydraulic support beyond the rated working resistance to achieve overload protection. Its main parameters include opening pressure and opening time. [0003] The rated support strength (working resistance) of the hydraulic support design is determined by the cylinder diameter of the support column, the number of columns, and the opening pressure of the safety valve. In field use, the ...
