Description

technical field

[0001] The invention relates to a remote control method and device, in particular to a remote control system and method for advanced detection and forecasting of a mine excavation working face. Background technique

[0002] During the development and excavation of the mine working face, unfavorable geological bodies such as soft layers, faults, and subsidence columns in front of the excavation are important geological factors that induce outburst disasters such as coal gas and water. The main task of advance mine forecasting is to identify hidden geological structures such as faults, broken zones, collapsed columns, goafs, etc. According to the distribution position of geological bodies and their water-rich conditions, corresponding safety measures should be taken in advance to ensure the construction safety of the development and excavation of the working face.

[0003] The existing geological advanced forecasting methods in the process of mine working face...
