摘要
通过Ca(OH)2对煤炭氧化、自燃倾向特性作用的试验测试、分析、研究,提出一种新的、廉价和可靠的措施,同时,通过对同一回采工作面不同位置煤炭取样试验研究,指出该回采面煤层自燃倾向危险性及分布状况。经过5年多的现场试验应用,取得令人满意的防治效果和经济效益。
This paper,based on the experimental study and analy-sis of the action of Ca (OH) 2 for oxidation and spontaneous combustion of coal,describes a new efficient,economic and convenient technical measures for the prevention of spontaneous combustion in the gob.Through the experimental study of coal samples taking from different positions in the same working face,the paper put forward the spontaneous combustion hazard and distribution of the coal seam in this working face.More than five years' on-the-spot applica-tion has obtained satisfactory preventive results and economic benefits.
