摘要
煤矸石场自燃区治理的关键和难点是对煤矸石场高温区进行立体探测,获取自燃区横向和纵向分布范围。利用覆盖层介质内部直接测温方法和同位素测氡法联合确定自燃区横向分布范围,然后利用钻探取芯和钻孔中测温确定矸石堆积情况及自燃区纵向分布范围和深度,综合获取自燃区立体分布。利用上述方法对陕北某煤矸石场进行探测,结果表明:横向上高温区主要集中在治理区域西北侧并具有向东南延伸的趋势,纵向上高温区主要集中在地表以下浅部至中部区域。该探测思路对确定煤矸石场自燃区分布范围是切实可行的,可为煤矸石场自燃区治理提供基础资料。
The key and difficult point to control spontaneous combustion area of coal gangue yard is to carry out three-dimensional detec-tion of high temperature area of coal gangue yard and obtain the transverse and longitudinal distribution range of spontaneous combustion area.The horizontal distribution range of spontaneous combustion zone is determined by the direct temperature measurement method in the overburden medi-um and the isotope radon measurement method.Then,the accumulation of gangue and the longitudinal distribution range and depth of spontaneous combustion zone are determined by the temperature measurement in drilling and drilling.Using the above method to detect a coal gangue yard in northern Shaanxi,the res ults show that the horizontal high temperature area is mainly concentrated in the northwest of the treatment area and has a trend of extending to the southeast,and the vertical high temperature area is mainly concentrated in the shallow area below the surface to the central area.The detection method is feasible to determine the distribution range of spontaneous combustion area of coal gangue yard,and can provide ba-sic information for the treatment of spontaneous combustion area of coal gangue yard.
