opencast ore dressing assessment

A methodology for cumulative impact assessment of opencast

Jan 02, 2013· It involved questionnaire checklists and a geographical information system for scoping of the impact assessment study, and the ISCST3 air quality dispersion model for the analysis of impacts. Its use was illustrated by a case study at an opencast iron ore mine. The methodology could identify a number of potentially significant cumulative impacts.

The Structure of Reclaiming Warehouse of Minerals at Open

Jul 01, 2017· Abstract. In the article performed an analysis of ore reclaiming and overloading point characteristics at modern opencast mines. Ore reclaiming represents the most effective way of stability support of power-intensive and expensive technological dressing process, and, consequently, of maintenance of the optimal production and set-up parameters of extraction and quality of finished

Opencast Mining an overview ScienceDirect Topics

S.K. Chaulya, G.M. Prasad, in Sensing and Monitoring Technologies for Mines and Hazardous Areas, 2016 Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also

Assessment of Whole Body Vibration Exposure of Mining

In TRB iron ore mines of JSPL, dozers produced high levels of vibration followed by dumpers, motor graders, loaders, and excavators. The WBV results showed that out of 17 HEMMs, vibration levels of 6 HEMMs exceeded higher A (8) value (0.90 m/s2 ) and VDV value (17 m/s1.75), 10 HEMMs exceeded medium A (8) value (0.45 m/s2 ) and VDV value (8.5 m

Water and energy assessment for dewatering in opencast

Dec 01, 2014· The prediction of ground water flow at different working level is important for the excavation of ore below water table in opencast mines. Different analytical methods have been discussed for estimating water inflows for mine (Singh and Atkins, 1985a, Singh and Atkins, 1985b).Rational method, time-area method, tangent method and Young and Prudhoe methods have

ab0cd Sub-sectoral Environmental and Social Guidelines

Open cast mining involves the removal of ore from seams relatively near the surface by means of an open pit (see figure below). These mines often occupy a large area of land for excavation of the ore and disposal of the overburden (the waste rock lying over the ore). This kind of mining operation typically involves the following 4 stages: 1.
