Description

Goaf monitoring device for gob-side roadway Technical Field The utility model belongs to the technical field of geological engineering monitoring equipment, and particularly relates to a goaf monitoring device for a gob-side roadway. Background Goaf monitoring is an important link in the exploitation process of underground mines such as coal mines. In the coal mining process, the coal seam is removed to form an empty area, namely a goaf, and a plurality of hidden dangers such as accumulated water, accumulated gas, a roof, a fire area and the like exist in the area, and the data are unknown and seriously threaten the safety production of a mine, so that the goaf is monitored and early-warned, geological disasters or secondary emergency of the mine are early-warned and forecasted, the mine enterprises can take countermeasures in advance, and meanwhile, the safety accidents are effectively avoided. The gob-side entry is to maintain the original stoping entry along the goaf edge behind the coal face, and the entry of the previous section is re-supported and reserved for the next section by adopting a certain technical means, so that the gob-side entry is one mode in the coal pillar-free mining technology. The gob-side entry retaining can recover resources to the greatest extent and avoid coal loss. In the existing goaf monitoring technical field, if all monitoring equipment is directly installed in a goaf, monitoring staff need to check the goaf frequently at multiple points, the goaf is large in range and unclear in condition, safety accidents are easy to occur in the checking process, and meanwhile, the monitoring equipment is multiple in connecting lines and is directly arranged in the goaf or a gob-side roadway, so that damage is easily caused or the passing of staff and other equipment is easily influenced. Disclosure of utility model Aiming at the problems, the utility model provides the goaf monitoring device for the gob-side roadways, which utilizes the gob-side roadways to orderly arrange goafs of the monitoring device, and simultaneously guides and protects the connecting cables, so that the whole monitoring operation process is safe and reliable.
