Monitoring and early warning method, device and system for advanced support and super back column in fully mechanized mining face

Abstract

The embodiment of the invention discloses a method, device and system for monitoring and early warning of forepoling super prop-pulling of a fully-mechanized mining face. The method comprises the steps that images of a prop-pulling area and an erecting area are obtained; and in one forepoling operation period, when it is determined that singe hydraulic prop pulling in the prop-pulling area existsbefore erection of a single hydraulic prop in the erecting area, alarm information is given. By means of monitoring the super prop-pulling behavior in the forepoling operation of the full-mechanized mining face, the violation behaviors that a worker does not carry out prop pulling according to rules and regulations during forepoling of the full-mechanized mining face, erecting is carried out afterprop pulling, or the erected supporting columns are less than pulling props are solved, so that the large-area and long-time empty roof of the end is avoided, and the occurrence probability of the local roof fall accident of the end caused by the empty roof is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of coal mine safety, in particular to a monitoring and early warning method, device and system for advanced support and super-return columns in a fully mechanized mining face. Background technique [0002] The end of the fully mechanized mining face is the place where the fully mechanized mining face connects with the air return roadway and the transportation roadway, that is, the intersection point between the mining face and the trough (the trough generally includes the transport trough and the return air trough). The area is characterized by large suspended roof area, many mechanical equipment, and frequent access of equipment and personnel. Especially, the roof at the end of the fully mechanized mining face is subject to concentrated pressure due to mining operations, difficult maintenance, and prone to roof accidents. Therefore, the end of the fully mechanized mining face is no...
