摘　　要：煤与瓦斯突出是影响煤矿安全生产的主要因素之一,具有软分层特征的构造煤其突出的可能性更大,在防治煤与瓦斯突出时应尤为重视。根据现场的勘探资料及揭煤时的煤层情况,结合对个别案例的研究,分析了主要地质构造与沉积环境对煤层厚度的影响,并初步建立了煤层厚度预测的理论模型,同时简要分析了软分层的发育对煤与瓦斯突出的影响,对煤层厚度的预测和防突工作具有一定的指导意义。Coal and gas outburst is one of the main factors influencing coal mine safety production and possibility of gas outburst is more likely to happen in tectonic coal with soft layer,so soft layer should be given particular attention when preventing and controlling coal and gas outburst.According to the field exploration data and seam situation in uncovering coal,combining the study of individual cases,the impacts of the main geological structure and sedimentary environments on coal thickness are analyzed,a theoretical model of the coal seam thickness prediction is initially established,and the impacts of soft layer development on coal and gas outburst are briefly analyzed,which is of certain guiding significance for coal thickness prediction and outburst prevention.
