Mine laneway slot wave distributed advanced detection system and method

Abstract

The invention belongs to the technical field of mining instrument detection in coal field geological exploration, and discloses a mine laneway slot wave distributed advanced detection system and method. The system comprises a host, a seismic source exciter, three acquisition stations, and three detectors. The seismic source exciter is used for generating a seismic source signal. The three detectors are respectively arranged right ahead the head of a roadway, on the left side wall of the roadway and on the right side wall of the roadway, are arranged in a regular triangle shape and are used forreceiving the seismic source signal sent by the seismic source exciter, and the signal output end of each of the three detectors is connected with one acquisition station through a data transmissionline. The three acquisition stations are connected with the host after being connected in sequence, and are used for converting seismic signals sent by the detectors into digital signals and sending the digital signals to the host. According to the invention, the abnormal trend and position in front of the roadway can be detected, and advanced detection of 100m is realized.

Description

technical field [0001] The invention belongs to the technical field of mining instrument detection in coalfield geological exploration, and particularly relates to a distributed advanced detection system and method for trough waves in mine tunnels. Background technique [0002] During the tunnel excavation process, geological anomalies such as faults, collapsed columns, and broken zones are often exposed without a plan, resulting in gas outbursts and abandoned tunnels. Among many structural detection equipment, seismic method is relatively accurate to detect structures, but the accuracy rate is difficult to exceed 50%. The current detection instruments have defects in both methods and equipment. For example, when the tunnel TSP detection method is used underground, due to coal There is a loose circle on the wall, the detection effect of the geophone is poor, and the structure position cannot be accurately detected; other seismographs also have similar problems, some of which...

Among many structural detection equipment, the seismic method is relatively accurate in detecting structures, but the accuracy rate is difficult to break through 50%. The current detection instruments have defects in both methods and equipment. For example, when the tunnel TSP detection method is used underground, due to coal There is a loose ring on the wall, and the detection effect of the geophone is poor, and the structural position cannot be detected accurately; other seismometers also have similar problems, some construction is time-consuming and laborious, and some are bulky and inconvenient to carry
