Abstract
本发明公开了一种利用荧光示踪剂进行上覆采空区积水量探测的方法，将探水装置伸入探水钻孔至采空区对应位置，根据探水装置顶端吸水棉的吸水情况，能快速判断当前探测区域是否存在采空区积水，若判断该区域不存在积水或者积水量较小，则继续下一钻孔。当根据探水装置初步判断某区域的积水量较大时，将荧光示踪剂注入该处积水区域，待荧光示踪剂在积水中扩散并均匀分布后，取样一定量的积水，检验该水样的荧光强度并与注入的荧光示踪剂强度进行对比，进而计算出该积水区域的积水量；从而能够迅速、准确探测采空区积水位置、积水面积和积水量的情况，确保采空区积水的准确疏放和遗煤自燃危险的有效防控，保障相邻回采面的安全开采。
