摘　　要：煤矸石是煤炭开采过程中产生的固体废弃物,由于利用价值低,通常被丢弃在矸石场,逐渐形成矸石山。煤矸石长期堆积过程中经常发生自燃现象,造成人员伤亡和环境污染。以山西省燕子山煤矿矸石山为研究对象,阐述了4种典型煤矸石堆积方式的特点,分析了4种堆积方式下矸石山内部区域的温度水平和CO、 O_(2)体积分数。结果表明:黄土隔离和黄土分层堆积方式能够有效抑制煤矸石山内部温度升高的过程,降低煤矸石的CO产量和O_(2)消耗量;在黄土分层堆积中,随着土层厚度的增加,矸石山自燃抑制作用增强。Coal gangue is a solid waste generated during the coal mining process.Due to its low utilization value,it is usually discarded in the gangue yard,gradually forming a gangue mountain.During the long-term accumulation of coal gangue,spontaneous combustion often occurs,causing casualties and environmental pollution.Taking the gangue mountain of Yanzishan Coal Mine in Shanxi Province as the research object,the characteristics of four typical coal gangue stacking methods were elaborated,and the temperature levels and CO and O_(2volume) fractions in the internal area of the gangue mountain under the four stacking methods were analyzed.The results show that the isolation and layered stacking of loess can effectively suppress the process of temperature rise inside the coal gangue mountain,reduce the CO production and O_(2consumption) of coal gangue;in the layered accumulation of loess,as the thickness of the soil layer increases,the inhibitory effect of spontaneous combustion of gangue mountain is enhanced.
