煤巷炮掘工作面煤与瓦斯突出预警系统的开发

Development of Coal and Gas Outburst Pre-warning System for Seam Gateway Blasting Driving Face

根据煤与瓦斯突出理论、模糊数学知识和计算机技术,研究开发了煤巷炮掘工作面煤与瓦斯突出预警系统,实现了计算机对煤巷炮掘工作面的突出危险性预测管理。该系统实现了由静态预测预报变为动态预测预报,由间隔预测预报变为半连续预测预报,可提高炮掘工作面煤与瓦斯突出预测的可靠性,并对有突出危险工作面进行及时报警,从而防止发生煤与瓦斯突出。采用钻屑指标法、瓦斯峰谷比值法、地质因素法和综合指标法作为突出预测方法,并将煤巷炮掘工作面的突出危险性划分为突出危险、突出威胁和无突出危险3类。

According to the coal and gas outburst theory, the fuzzy mathematics knowledge and the computer technology, a coal and gas outburst pre-warning system of the seam gateway blasting driving face was researched and developed and the computer could be applied to the outburst danger prediction management of the seam gateway blasting driving face. The system could implement the static prediction and forecast changed to the dynamic prediction and forecast and the interval prediction and forecast changed to semi-continued prediction and forecast, which could improve the reliability of the coal and gas outburst prediction of the seam blasting driving face and could have an on time pre-warning for the face with the outburst danger in order to prevent the coal and gas outburst occurred. The drilling cutting index method, gas peak-valley ratio method, geological factors method and comprehensive index method could be applied to as the outburst pre- diction method to classify the outburst dangers of the seam gateway blasting driving face into three grades, such as the outburst danger, outburst threats and no outburst danger.
