北京地区许多废弃的无主老矿山未实施矿山环境治理和土地资源恢复工程,矿区内地质环境和生态条件恶劣。本文对废弃矿山及其治理工程特点进行了分析,运用灰色关联度分析法,阐述了矿山废弃地土地资源破坏效应的四个因素——地表景观效应、土体污染效应、次生灾害效应、生态环境之间的联系。以房山区石窝大理石矿山废弃地治理工程为例,提出了矿山废弃地治理以矿山环境、灾害治理为主,以园林景观绿化为辅相结合的二维治理模式,在地形整治、挡土墙、绿化等措施的基础上进行园林景观的设计,结合周边居民生活需求,利用矿区内的正负地形渣堆和采石坑,进行景观的再生和组合,将采石坑设计成下沉式休闲公园和健身广场,希望通过园林景观绿化工程的实施,改善矿区及周边地表景观和生态环境。 相似文献

河南信阳—安徽庐江断裂带中,出露有中生代裂隙式喷溢形成的火山岩体。在火山岩中具有多期多次活动形成的熔结火山角砾岩。有趣的是,在河南信阳东部的大石窝一带,熔结火山角砾岩体长达几十千米,宽几千米。在采石场和采石坑中竟没有一条断裂或节理;熔结火山角砾岩中的角砾大小不一,多为0.5cm～5cm之间,没有层理;令观者称奇。 相似文献

我国古代采石业发展辉煌,具有规模大、历时长、遗留采石遗迹众多等特征,其中尤以浙江省的石材开采最为著名,因古代石材开采所遗留的众多古采石场目前都得到了极好的再利用。浙江省温岭市长屿硐天大型古地下采石场目前已被纳入世界地质公园及国家矿山公园。在现场考察过程中,发现了古代采石者所创造的一套由"探"、"扩"、"避"、"采"、"排"、"运"、"填"等7个主要工序所组成的长屿采石古工法。作为古代地下采石遗迹,长屿硐天拥有以水云硐大型古洞室群为典型代表的28个大型古洞室群,总体规模巨大。该工艺的发现,说明古代采石者从长期工程实践中所创造的长屿采石古工法是行之有效的。进而研究得出,他们所创的采石古工法其合理性,不仅在于其充分考虑了当时采石工具的材质条件,而主要在于其适应了当地的工程地质条件。 相似文献

Today, waste is an important environmental problem that needs to be solved. The way it is collected and managed should be considered with respect to the negative impact on the environment. Although the Atabey aggregate quarry was operated with natural sand-gravel until 2 years ago, it was closed due to technological renovation in the crushing-screening unit and uneconomic production. This area was later used by the Atabey Municipality as a waste storage area. Thus, uncontrolled storage occurred at the quarry site. As a result, new, more intensive environmental problems have emerged in the area, such as visual pollution and the pollution of groundwater. This paper evaluates the impact of municipal solid waste disposal in an abandoned quarry site on groundwater, land surface temperature, land surface moisture, and vegetation cover using GIS (Geographic Information Systems) and remote sensing technologies. According to the obtained results, the solid wastes stored in the area caused groundwater pollution, increased surface temperature, and reduced soil moisture. 相似文献

The development of large-scale bedrock quarry operations often requires high-volume and long-term groundwater extraction to maintain a sustainable working environment. These dewatering activities often influence groundwater levels and flow patterns regionally. In the present study, the influence of the dewatering of the travertine quarry operations near the city of Tivoli, Italy, are quantitatively investigated through an integrated analysis of field data and numerical modeling. Lowering of regional groundwater levels in the vicinity of the quarry has led to destructive land subsidence and alterations to the flow system sustaining a hot-spring area. The study employs a finite element numerical model (FEFLOW) to evaluate and quantify the impact of the extensive dewatering on fault-controlled regional groundwater flow in the Acque Albule basin. By incorporating the physical field data and historical hydrologic information, the numerical model was calibrated against three groundwater scenarios, reproducing the effects of different exploitation activities, coupled with natural changes over the course of the quarry operation. The results indicate that groundwater withdrawals by the mining industry and by “Terme di Roma” spa resulted in the cessation of flow from the primary thermal spring and a drop in the phreatic level in the area consequently affected by land subsidence. 相似文献

Liners are commonly used in engineered waste disposal landfill to minimize the potential contamination of the aquatic environment. The adsorption behavior of Cu(II) from aqueous solution onto clay admixed with various mix ratios of quarry fines was investigated. The amount of Cu(II) adsorption increases with increase in contact time. The copper removal efficiencies of the composite mixture gradually decrease from 94.53 % (raw clay) to 85.59 % (20 % of quarry fines with clay), and appreciable decrease in percent removal 75.61 % was found with 25 % of quarry fines with clay. The kinetic adsorption data were analyzed by pseudo-first-order, pseudo-second-order, Bhattacharya–Venkobachar and Natarajan–Khalaf kinetic models to classify adsorption process mechanisms. Kinetic experimental data were good agreement with pseudo-second-order kinetic model with the degree of fitness of the data (R 2) 0.9999 for the adsorption of Cu(II). The results revealed that quarry fines can be used with optimum of 20 % replacement of natural clay for removal of Cu(II) as a liner material in landfills. 相似文献

Sediments of Manaveli Formation (Palaeocene) are studied from the Thondaimanattam quarry section and Manaveli section of the
Pondicherry area, which comprises of bioturbated arenaceous limestone-shale and shaly-sandstone sequences respectively. These
sediments consist of high density and low diversity trace fossil genera which includes Lanicodichnus, Ophiomorpha, Planolites, Palaeophycus, Skolithos, Thalassinoides, and Polychaetes tubes. The abundance of horizontal structures of the Thondaimanattam quarry section indicate low to moderate
wave and current energy in fully marine subtidal environments while the presences of vertical structures of the Manaveli section
indicate moderate to high wave and current energy in the marginal marine environment of deposition for the Palaeocene sediments
of the Pondicherry area. 相似文献

Water seepage to ground surface at a limestone quarry located at Wadi Garawy about 20 km south-east of Helwan city in Egypt posed a real threat to the mining activity at the quarry. The quarry area is known to be very dry for decades and away from water utilities and infrastructures that may cause water leaks to the quarry. Geophysical investigation including 1D Vertical Electrical Sounding (VES), 2D Electrical Resistivity Tomography (ERT) and 1D Transient Electromagnetic (TEM) surveys were conducted to characterize the rock sequence and locate what could be a possible source of water seepage to the quarry. The resistivity profiles generated from the VES and TEM surveys mapped the rock units in the area down to depths exceeded 100 m. The ERT profiles acquired from the quarrying zone close to the water seepage spot have imaged the top of groundwater level at few meters below the ground surface at the quarry open pit. The spot of groundwater seepage seemed to occur at an area of limestone dissolution that were filled by finer sediments. The finer sediments acted as a hydrological conduit that allowed an upward seepage of groundwater to ground surface under the capillary action effect. 相似文献
