摘要:
通过对掘进工作面前方煤体的受力特点进行分析,理论研究了掘进工作面应力分布特征,得出了掘进巷道前方卸压带宽度计算公式,分析了各因素对煤与瓦斯突出发生的影响,现场利用电磁辐射监测技术进行测试,与理论计算结果相吻合。结果表明,掘进工作面前方卸压带的宽度与巷道的高度、巷道煤岩与顶板的摩擦角等因素有重要关系,研究为掘进工作面煤与瓦斯突出预测及防治具有重要的指导意义。
Abstract:
Through analyzing the stress characteristics and researching the law of distribution on the coal body of roadway head, the calculation formula to ascertain the stress relaxation zone was evolved. The various factors on coal and gas outburst were discussed. Combining with field tests and theoretical calculation, the result was Tproved to be trusted. The research showed that the width of stress relaxation zone in the roadway head is related to height of rooffloor and the frictional angle of the coal. It provides an important guiding significance for coal and gas outburst prediction and prevention.
