Characteristics of loose sediments in the mine.

Rock stratum	Bottom boundary depth (m)	Thickness (m)	Hydrological parameters	Lithology	Watery
Central aquifer	369.70∼378.40	34.70∼70.60	Q = 5.747	Sand and clay	Medium
			q = 0.504
			h = 19.16
Central aquiclude	404.40∼441.20	39.25∼64.00	q = 0.0019	Sandy clay	Poor
Lower aquifer		0∼3.50	Q = 5.747	Sandy clay	Poor
			q = 0.00485
			h = 10.228
Lower aquiclude	440.55∼461.35	0∼46.10		Calcareous clay	Poor
Bottom “red bed”		0∼3.65	q = 0.0016	Yellow clay	Poor

Note: h denotes the elevation of static water level in m; Q refers to the water consumption in L/s; q is the water consumption in L/(s·m).
