Mine positioning system

Abstract

The invention provides a mine positioning system which comprises a ground host, electric wires distributed in all mine laneways and portable communicators arranged for all working staff. The electric wires comprise one or two line sets. Each line set comprises a trunk line and branch lines, wherein the trunk line and each branch line respectively comprise a positive line and a negative line, the positive line and the negative line of the trunk line are identical in potential, and the positive line and the negative line of each branch line are identical in potential. Sockets are arranged at proper intervals on each trunk line. Sockets are arranged at proper intervals on each branch line. Two jacks of each socket are connected with the corresponding positive line and the corresponding negative line respectively. A waterproof cover is further arranged on each socket. The host comprises a host power amplifier and a host loudspeaker. Each communicator comprises a communication microphone, wherein two pins are led out of the communication microphone and correspond to the two jacks of the corresponding socket. The mine positioning system is low in engineering cost, suitable for wide construction, and capable of realizing reliable communication between trapped people and ground personnel under the condition of a mine accident so that the ground personnel can know the specific positions and conditions of the trapped people accurately and timely.

Description

[0001] technical field [0002] The invention relates to the field of mine facilities, in particular to a personnel positioning system inside a mine. [0003] Background technique [0004] In the process of mine operation, without the construction of communication facilities, due to the problem of electromagnetic shielding, the staff in the mine cannot use handheld communication devices to communicate directly with the ground. [0005] Therefore, in order to improve the safety of the staff, it is usually required to configure a communication system in the mine. The most common ones are underground wireless communication transfer stations, leaking cables, etc.; however, due to the huge investment in such communication facilities, more mine managers have to If the cost is reduced, the configuration will be abandoned, which will trap the underground workers in a very dangerous working environment; this situation is especially common in more private mines and black mines.

Problems solved by technology

[0004] In the process of mine operation, without the construction of communication facilities, due to the problem of electromagnetic shielding, the staff in the mine cannot use handheld communication devices to communicate directly with the ground

[0005] Therefore, in order to improve the safety of the staff, it is usually required to configure a communication system in the mine. The most common ones are underground wireless communication transfer stations, leaking cables, etc.; however, due to the huge investment in such communication facilities, more mine managers have to When the cost is reduced, the configuration is abandoned, thus trapping underground workers in a very dangerous working environment; this situation is especially common in more private mines and black mines

[0006] On the other hand, even if the current professional communication system is installed in the mine, there are still problems that are difficult to overcome; the problem is that as long as the wireless system is used, once an accident such as a collapse occurs in the mine, the staff is very likely to be blocked. After the blockage, the wireless signal is also shielded from the collapse; resulting in the inability to communicate externally; and the use of leaky cables will not be able to detect the specific location of the trapped people, which will still cause great difficulties for search and rescue work

[0007] It can be seen that the current personnel positioning system in the mine not only has a huge engineering cost, but also is difficult to reliably locate the trapped personnel under accident conditions; the majority of mine workers have been in a very dangerous working environment
