Research On Karst Characteristics And Its Hydrologic Property Of XiGuoDing Limestone Deposit In Ning-Zhen Mountain

Limestone is an important nonmetallic mineral and primarily karstifical rock on the earth, In the perambulation of the limestone mineral deposit, the diggings' s karst development regulation and its monitoring groundwater is the main engineering problem of mineral deposit hydrology geology, these research about karst development regulation and its monitoring groundwater have important fulfillment meaning.In the foundation of geologic expatiate about stratum, rock and construct characteristic, analyzing in details the thin and tiny view in composition, the relation of karst with rocky structure ,its mineral characteristic , chemic component. Analyzing the relation of the terrain physiognomy, weather, hydrology with karst, Opening out the relation of karst with fault and drape on the leveland perpendicular direction, Classing the diggings' s karst and analyzing its fillings ( include the modern and ancient rock), dividing diggings into section, including along the level directional and perpendicular. From the analysis of the mineral bed cause of formation, opening out the relation of karst and the I, II, EH layer mineral accumulate environment, According to groundwater trial data of the spring, well and drill, analyzing and researching groundwater' s replenishment, path flow, drainage, announcing the conversion relation of karst groundwater with atmosphere water, surface water" three waters" , its dynamic characteristic and basic characteristic of groundwater chemistry field etc.The article sumed up completely the diggings karst development regulationand its monitoring groundwater:1) the region' s rainfall characteristic, geography characteristic, stratum rock characteristic is a basic factor to affect karst development, drape and faultage characteristic is a predominant factor to affect karst development.2) the karst' s appearance, scale and its extanding controled the gathering and carrying of the karst groundwater , groundwater' s replenishment, path flow, drainage promoted further the karst development, the diggings groundwater enrichment is each to karst development.
