摘要
为查明齐大山露天铁矿西帮各含水层组的岩性和富水性、埋藏条件、地下水补给及径排条件,确定齐大山矿西帮区域岩土体密度和渗透系数;选择构成露天边坡的主要岩石,采用ZYS-1煤岩多功能三轴渗透仪在室内测定岩样渗透系数参数,并对现场5个不同位置的边坡土样进行密度和渗透系数测定。试验结果表明:齐大山矿西帮主要岩样在渗流作用影响下岩石整体性较好,作为基岩层可以有效的阻隔地下水渗流。
In order to find out the lithology, water abundance, burial conditions, groundwater recharge and runoff conditions of each aquifer group on the west slope of Qidashan Open-pit Iron Mine, the article determines rock and soil density and permeability coefficient, selects the main rock of slope, adopts zys-1 coal rock multifunctional triaxial permeability instrument to measure the permeability coefficient parameters of rock samples, and measures the density and permeability coefficient of slope soil samples at five different locations on site. The results show that the main rock samples of Qishan Mine are good under the influence of seepage, and as a bedrock layer can effectively block groundwater seepage.
