1.引言 本文叙述了笔者自1964年以来,在沃里克郡、南德比郡和莱斯特郡一些煤田控制自然发火方面的经验。 在这个时期南米德兰地区的许多煤田发生了几百起自然发热。其中以沃里克郡的厚煤层,本奇煤层,南德比郡的梅因煤层和莱斯特郡的下梅因煤层、朗特煤层最为严重。这几种煤层长期以来具有自燃倾向,且危险性很大,使得沃里克郡的多米尔煤矿和南德比郡的卡德利赫尔矿分别在1968年、1975年险些报废关闭。 1. INTRODUCTION This article describes the author’s experience with controlling spontaneous combustion in some coalfields in Warwickshire, South Derbyshire and Leicestershire since 1964. Hundreds of natural heats occurred in many coal fields in southern Midlands during this period. Among them, the thick coal seam of Warwickshire, Bench coal seam, Maine coal seam of South Derbyshire and Lower Maine coal seam of Leicestershire are the most serious. These types of seams have long tended to be spontaneous and dangerously dangerous, leaving Doom Coal Mine in Warwickshire and Cadeliger Mine in South Derbyshire almost scrapped in 1968 and 1975, respectively.
