地形复杂地区煤层地温等值线绘制方法初探

Preliminary Research to Mapping the Ground Temperature Contour of Coal Seams in Karst Peak-cluster Geomorphology

查明井田内的地温分布状况是煤田地质勘探的重要任务之一,特别是石灰岩较发育地区及地形切割严重地区,由于岩溶较发育,形成的喀斯特峰丛地貌对煤层埋藏深度影响较大,煤层埋深无规律变化是影响煤层地温不均匀的主要因素。查明煤层地温的分布情况是龙永煤田生产建设中的一个重要问题。探讨了福建山区地貌与喀斯特峰丛地貌条件下的煤层底板地温等值线绘制方法。

Identification of the ground temperature is one of the important tasks for Longyong coal-field geological exploration, especially in the area with limestone and karst well-developed, where the formed karst peak-cluster geomorphology heavily affects the depth of coal seams and becomes the main factor to irregular changes of ground temperature of coal seams. A new method is presented for mapping the ground temperature contour of the floor of coal seams in the area of hills of Fujian and karst peak-cluster geomorphology.
