Software Design and Application of a Combinatorial Algorithm on Safety Early-warning System for the Working Face in Mine

Based on analyzing the contents of safety early-warning system for the working face in mine and according to the production characteristic of coal mine in China, combining the analytical hierarchy process and neural network BP algorithm. The safety early-warning system for the working face in mine was also designed based on the combinatorial algorithm. The system was applied to estimate support capacity and forecast the ground pressure of working surface in Xinan mine. The forecasting result proves that this method is very useful.
