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...

Problems solved by technology

Accordingly, if the seismic reflection wave method in coal mines uses a hammering source, the energy is small, and the need for long-distance advanced detection cannot be realized. At the same time, due to the influence of the loose circle of roadway excavation, the consistency of the number is poor, which affects the detection effect

However, if the form of multi-shot excitation is adopted, the interval between two shots will be long, which is not only a severe challenge to the working time of portable mine instruments, but also cannot meet the needs of high-yield and high-efficiency mines.
