Environment monitoring system for underground goaf of coal mine

Abstract

The invention relates to an internal environment parameter monitoring system for an underground goaf of a coal mine. The monitoring system mainly comprises the following parts: terminal monitoring nodes, router nodes, a receiving device, an Ethernet server and an upper computer. The terminal monitoring nodes are arranged along the working face and can monitor environment parameters of a goaf. The router nodes are arranged at each distance, the router nodes collect terminal node data and transmit the terminal node data to the receiving device, and underground monitoring personnel obtain internal environment parameters of the goaf through the receiving device. The receiving device synchronizes data to the Ethernet server through a WiFi module, is connected with the ground upper computer through an optical fiber and transmits the data, and the monitoring personnel monitor the temperature of an oxidation zone of the goaf through obtained internal environment parameters of the goaf. A data basis is provided for work such as reasonable working face advancing speed making, gas extraction design, early warning and emergency plans, and intelligent mine construction is further improved.

Description

technical field [0001] The invention designs an underground coal mine monitoring device, and in particular relates to an environment monitoring system for an underground coal mine goaf. Background technique [0002] In the process of coal mining, due to the difficulty of mining, the slow speed of advancement, the natural collapse of the gob takes a long time, the corners of the working face have air leakage, and the coal left in the goaf is easy to combine with oxygen to undergo oxidation reactions. Spontaneous combustion of coal exists. Spontaneous combustion of coal can easily lead to multiple disasters in underground mines, endangering the life and property safety of underground workers. It is difficult to determine the internal temperature of the goaf, and it is impossible to know the high temperature points in the gob specifically. The traditional temperature monitoring system adopts optical cable, optical fiber and other wired transmission methods, which have a wide ...
