Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The embodiment of the present invention recognizes the production state of the working face based on the methane sensor monitoring value of the underground working face and the start-stop state of major equipment (such as coal shearers and roadheaders), that is, the coal mining face and the driving face of the coal mine are currently in the production state Still discontinued.

[0026] Taking the underground working face of a coal mine as an example, the historical production status of the coal mining face can be identified based on the methane sensor monitoring value of the coal mi...

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 ...
