| 摘 要： | 本文根据陕西神府煤田煤层自然面积大、强度高、延展深的特点,研究了自燃的基本特征和分布规律.提出了煤层自燃的三级烈度,探索了煤层自燃使煤层变薄与形态以及自燃区大小与煤层结构及厚度的关系、对煤质和自燃煤层范围大小的影响等。通过野外观察和勘探实践,提出了有效的勘探方法与辅助手段。对确定煤层纵横边界线、探明自燃区煤田储量有重要意义。

| Abstract: | According to the characteristics,large spontaneous combustion area,high strength and deep extension of coal seams in Shaanxi Shenfu coal field,the basic features of spontaneous combustion and its distribution rules have been stuided.The author proposes the concept of spontaneous combustion intensity, which is divided into three grades,discusses the thinning of coal seams due to spontaneous combustion and the forms after thinning,the relation of its area size with the texture and thickness of coal seams and the influences on maceral and spontaneous combustion range of coal seams. Through observation in the field and prospecting practice,the effective prospecting method and supplementary means are put forward,those possess great significance for determining the boundary of coal seams in all dire- ctions and detecting the coal field reserves of spontaneous combustion. |
