摘要
科学地圈划出煤田露头火区的燃烧范围,是提出更加合理可靠的煤田露头火区防治措施的指导依据。在分析煤田露头火区引起地表沉陷机理与范围的基础上,进一步研究了火区上覆岩层的岩性、煤层的倾角、煤层燃烧深度、煤层燃烧厚度、燃烧煤层数量等因素对火区塌陷范围的影响。提出了依据煤田露头火区燃烧三要素,分别从岩层移动、通风系统和火区热源3方面来分析确定煤田露头火区燃烧范围的方法。
It is the guidance to scientifically determine the combustion scope of the coalfield outcrop fire area for proposing more reasonable and reliable prevention and control measures basis for coalfield outcrop fire. On the basis of the analysis of the mechanism and range of the coalfield outcrop fire area causing subsidence, we further study on the influence factors for the fire area subsidence range, such as the lithology of overlying strata, the inclination angle of coal seam, the burning depth of coal seam,the burning thickness of the coal seam, the burning quantity of the coal seam, and so on. This method for determining the scope of the fire burning is proposed on the basis of the three factors of coalfield outcrop fire burning, such as the movement of stratum,the ventilating system and the heat source of fire area.
