Embodiment 1

[0037] Such as image 3 The shown through-the-ground communication system includes a network centralized controller and several wireless gas concentration sensors, the wireless gas concentration sensors include a microprocessor, and a through-the-ground communication positioning module and a gas concentration measurement module (capable of detecting CO , O 2 、CH 4 Such as n kinds of gas concentration), battery. Based on the system, the present invention proposes a method for measuring the gas concentration of an underground goaf, comprising the following steps:

[0038]Arrange the network centralized controller in the underground roadway, and then arrange the wireless gas concentration sensor. You can choose to arrange it before or after the collapse of the goaf, that is, before the collapse of the goaf in the underground, arrange more than three sensors in the goaf Wireless gas concentration sensors, wherein the coordinates of the three wireless gas concentration sensors a...

Embodiment 2

[0045] The present invention utilizes a wireless network system with a ground-penetrating communication function, which can penetrate rocks, soil layers, water, minerals, etc. According to different media, the ground-penetrating communication distance can reach 10-100 meters, such as image 3 As shown, it includes a network centralized controller arranged in the underground roadway, more than three wireless gas concentration sensors arranged in the underground goaf, each wireless gas concentration sensor includes a microprocessor, and a transparent sensor connected to the microprocessor. The ground communication positioning module, the gas concentration measurement module and the battery, and the wireless gas concentration sensor send the node positioning information and gas concentration measurement information to the network centralized controller through the ad hoc network within the communication range.

[0046] Such as image 3 As shown, the wireless gas concentration sen...

Abstract

The invention relates to a gas concentration measurement method and system for an underground goaf. The method and system has the advantages that a network centralization controller is arranged in anunderground tunnel, and wireless gas concentration sensors are arranged in the goaf; and in case of occurrence of a fire or gas concentration over-limit prewarning somewhere in the goaf after the goafis collapsed, the network centralization controller collects gas concentration measurement information and positioning information uploaded by the wireless gas concentration sensors, so that a gas concentration distribution field can be drawn, an occurrence position of a fire accident or the gas concentration over-limit prewarning can be precisely determined, the working personnel can be notifiedto pertinently take measures in a timely manner for efficient 'targeted' handling, life safety of the underground working personnel and other property safety can be effectively protected, a visual data basis can be provided for reasonable working surface stoping speed designing, tunnel layout designing, gas extraction designing, fire prewarning, emergency rescue and other work of a mine, the information level of the mine can be greatly improved, and refined management of the mine can be achieved.

Description

technical field [0001] The invention belongs to the technical field of ground-penetrating communication, and in particular relates to a method and system for measuring gas concentration in an underground goaf. Background technique [0002] Underground operations such as mines, subways, and tunnels have complex and dangerous environments, and safety accidents often occur, such as water penetration, rock bursts, landslides, underground gas explosions, and fires. Traditional communication methods can meet the needs of daily command and dispatch, personnel positioning, and communication up and down the mine, but accidents will destroy the existing communication channels, causing disconnection of wired communication lines and interruption of communication, resulting in the inability of ground personnel to know the status of trapped underground personnel in a timely manner. The specific situation will affect post-disaster rescue. Therefore, the traditional mine communication syste...
