Spontaneous combustion(sponcom) is one of the issues of concern with the blasting gallery(BG) method of coal mining and has the potential to cause fires, and impact on production and safety, greenhouse gas(GHG) emissions and huge costs involved in controlling the aftermath situations. Some of the research attempts made to prevent and control coal mine fires and spontaneous combustion in thick seams worked with bord and pillar mining methods are presented in this paper. In the study, computational fluid dynamics(CFD) modelling techniques were used to simulate and assess the effects of various mining methods, layouts, designs, and different operational and ventilation parameters on the flow of goaf gases in BG panels. A wide range of parametric studies were conducted to develop proactive strategies to control and prevent ingress of oxygen into the goaf area preventing spontaneous combustion and mine fires.

月圆之夜,人变身成狼……这似乎只存在于魔幻故事中。澳大利亚研究人员观察发现,满月确实会诱发人性中的“狼性”,令人脾气暴躁,更具暴力倾向和攻击性。  研究显示,在过去的一年时间里,共有91名具有暴力倾向和攻击性的病人被送往醫院急诊部。其中21人在满月时被送至医院,是另外7种月相时的两倍。对此专家解释说,月球引力也能像引起海洋潮汐那样对人体中的液体发生作用,称之为生物潮。满月时,月亮对人的情绪影响比较
