Cemex Limestone Quarry RESPECCemex operates a limestone quarry near Wampum, Pennsylvania, that supplies the feed to their nearby cement factory. The quarry had traditionally been mined using surface methods, but while extracting the Vanport Limestone, the mining ratio began to increase. Because the mining ratio can determine when the current mining method becomes uneconomical, and because the min

  • Study of Factors Behind Rock Slope Displacement at

    At Higashi Shikagoe limestone quarry located in Minami Furano, Hokkaido, Japan, an automated polar system (APS) was set up to monitor rock slope deformation. The system consists of a laser beam generator (at the base point) and 16 mirror points ( Figure 1 ). 12 of the mirrors are installed on the rock slope of the mountain type quarry.

  • The Second Quarry Diesel Somewhere, Wales

    326ensp;0183;ensp;The Second Quarry Diesel was a diesel engine purchased by the Limestone Quarry in early 1948. It was purchased to replace the aging Rutley, who had been working on the railway and later the quarry for nearly twenty years and had become costly to maintain.It is said to have been not only smaller, but also a lot stronger than Rutley had been even at his peak, which led to it fully replacing Groundwater monitoring of an openpit limestone

    Groundwater flow and its geochemical evolution in mines are important not only in the study of contaminant migration but also in the effective planning of excavation. The effects of groundwater on the stability of rock slopes and other mine constructions especially in limestone quarries are crucial because calcite, the major mineral component of limestone, is moderately soluble in water.
