Abstract

The invention provides a method and a device for identifying the working state of an underground working face and a production decision system. The method comprises the following steps: acquiring methane concentration data of the underground working face in a preset time period; identifying the operation state of the underground working face according to the methane concentration data, wherein the operation state comprises a production state or a production stop state. According to the embodiment of the invention, the working state of the working face is judged through the methane concentration data of the underground working face, judgment is performed only based on the basic data provided by the working face, the universality is higher, the timeliness and accuracy of obtaining the working condition are higher, and accurate mine production conditions can be provided for different functional departments; and thus, the system is assisted to make a safety production scheduling guidance decision.

Description

technical field

[0001] The invention relates to the technical field of coal mine safety production data feature recognition, in particular, to a recognition method, device and production decision-making system for the working state of an underground working face. Background technique

[0002] In the process of coal mining and excavation in coal mines, gas will gushes out from the coal wall, the mined coal will also emit gas, and the goaf may also gushes out gas. Gas accidents are the main cause of coal accidents in recent years. Monitoring the gas concentration is an important means to avoid gas accidents. The speed of gas overflow is different during the production period and the shutdown period of the coal mine, and the gas concentration during the production period is higher.

[0003] In the process of coal mine production, different functional departments have different concerns: the management and scheduling department pays more attention to the production situation of ...
