Infrared Radiation Temperature Experimental Studyof Physical Simulation Of Wangtaipu Coal Mine Wongawilli Mining Method

In this article, through analog simulation wongawilli filling mining method to study the short wall mining infrared radiation temperature change rule, in the process of the large three-dimensional numerical calculation software FLAC3 D is adopted to wongawilli filling stope mining method for a numerical simulation of roadway surrounding rock stress and deformation law, seek infrared radiation in the infrared radiant heat like figure temperature abnormal area, and the temperature change of infrared radiation anomaly zone average infrared radiation temperature on quantitative analysis of the experimental results of wongawilli filling mining method of rock pressure control has a certain guiding significance.In the infrared radiation temperature experiments, interference factors on the influence on the result of the experiment, and also due to the irreversible interference factors, complexity and randomness, through the theoretical calculation of the infrared radiation is not feasible, has not been previous denoising method separation to remove the interference of external factors, this paper put forward the reference area denoising method, based on the internal factors under the condition of basic stability, surface average infrared radiation temperature basically stable relatively small principle, through reference to regional average infrared radiation temperature curve to remove all outside influence factors of the infrared radiation, which is more real surface average infrared radiation temperature, and the evaluation of this article provides Suggestions for the choice of correlation coefficient as a reference standard.This paper analyzes the different stages of stope drift infrared radiant heat like figure variation characteristics, and stope drift excavation influence within the scope of the average infrared radiation temperature variation characteristics, main research results are as follows:(1) by analyzing the different stages of stope drift characteristics of the infrared radiant heat like figure, can see clearly the monitoring area the temperature anomaly zone around the stope drift, and the temperature anomaly area infrared radiation temperature and the temperature anomaly area.(2) all stope drift excavation before denoising method of denoising by the reference area, average infrared radiation temperature fluctuations small, average infrared radiation temperature variation curve is basically stable, amplitude in the range of 0.10 ℃.(3) at different stages after the stope drift excavation average infrared radiation temperature changes impact scope, mixed, haphazard. But influenced by excavation disturbance, four stages of stope drift excavation influence within the scope of a larger average infrared radiation temperature fluctuations, maximum fluctuation is 0.26 ℃.
