Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings.
[0019] The present invention is based on the ANN method for predicting and forecasting small structures ahead of coal roadway excavation, and the specific implementation technical scheme includes the following steps:
[0020] 1. Analyze and determine the influencing factors closely related to the distribution and development of small coal seam structures in the study area
[0021] The analysis of factors closely related to the distribution and development of small structures in the study area includes the analysis of coal seam information related to small structures in the study area and the logical reasoning of the "encircling principle" in the prediction of small structures.
[0022] The analysis of factors closely related to the distribution and development of small structures in the study area includes:
[0023] (1) Changes in the occurrence of fractures in the co...
