【摘要】：較高精度的煤與瓦斯突出預測是煤礦安全生產(chǎn)的必要前提和保證。為了實現(xiàn)對煤與瓦斯突出危險性快速、準確和動態(tài)預測,考慮煤與瓦斯突出多種影響因素。提出一種改進的概率神經(jīng)網(wǎng)絡(luò)(PNN)煤與瓦斯突出預測模型。首先,引進一種對稱Alpha穩(wěn)定分布(SαS),SαS有更廣泛的數(shù)學表達,其徑向?qū)ΨQ特性可充當PNN樣本層中的高斯分布。在SαS的基礎(chǔ)上,建立煤與瓦斯突出危險性預測的SαS-PNN模型。將SαS-PNN模型應(yīng)用于國內(nèi)26個典型礦井的煤與瓦斯突出危險性等級預測。預測結(jié)果表明:在3種不同的訓練和測試下SαS-PNN模型仍具有良好的預測效果,其誤判率分別為7.69%、11.54%和15.38%。說明該模型可為煤礦開采中煤與瓦斯突出危險性預測提供了一種可能的思路。
[Abstract]:High precision prediction of coal and gas outburst is the necessary premise and guarantee of coal mine safety production. In order to realize fast, accurate and dynamic prediction of coal and gas outburst, Considering the influence factors of coal and gas outburst, an improved probabilistic neural network (PNN) model for predicting coal and gas outburst is proposed. The radial symmetry can act as Gao Si distribution in PNN sample layer. The S 偽 S-PNN model of coal and gas outburst risk prediction was established. The S 偽 S-PNN model was applied to the prediction of coal and gas outburst risk grade in 26 typical mines in China. The prediction results showed that S 偽 S-PNN model was used in 3 different training and testing conditions. Still have good prediction results, The misjudgment rates are 7.69% and 15.38%, respectively. It shows that the model can provide a possible way to predict the risk of coal and gas outburst in coal mining.
