We have more than twenty years of experience in providing world class integrated services in mining and construction, to open pit and underground operations. Our services span all phases of a mining project, comprising mine planning, development, construction, and operations, through to mine rehabilitation
Mining leases and concessions are linked with rehabilitation conditions and the obligation to comply with government regulations. Many operations make rehabilitation the responsibility of individual production staff by including rehabilitation targets in their performance appraisals.
Jun 25, 2019 · Thus an open pit mine requires a road network which connects the extraction sectors inside the pit to all possible destinations outside the pit (Yarmuch et al., 2017). Inpit ramps are roads that connect the working faces to the pit exits these require the removal of a great amount of material for their construction.

This guidance material is seeking to increase the awareness of one particular area of risk in open pit mining and quarrying and to encourage appropriate methods for identifying, quantifying and managing the risks. For further information on risk concepts, refer to AS/NZS ISO 31000:2009 Risk management Principles and Guidelines.
Mining and industrial activities are the primary sources of soil pollution in the openpit coal mine. The concentrations of PAHs in 11 sampling sites in the industrial district and 9 sampling sites with different land use types in Pingshuo openpit coal mine, China, were measured to investigate the distributions of PAHs and possible sources in soil profiles (0–100 cm).
PDF Mining activities are the integral part of societal development. However, the mitigation of mine impacted environmental and social issues warrant a corrective action supported by appropriate
Abstract: The environmental, social and economic problems associated with abandoned mine sites are serious and global. Abandoned mines may pose unique and complex challenges, often leaving negative impacts such as: safety and health hazards for people and animals, neglected mining heritage and other assets, in addition to economicallydepressed communities.
Abstract. It is well known that mining activities have negative impacts on surface and subsurface water quality. These impacts could cause an environmental disaster, especially when necessary mitigation and rehabilitation activities are not implemented.
Abstract. Similar to the mixedinteger programming library (MIPLIB), we present a library of publicly available test problem instances for three classical types of open pit mining problems: the ultimate pit limit problem and two variants of open pit production scheduling problems.

Abstract: A hierarchical openpit mine production scheduling methodology linking the optimal strategic open pit mine plan to the optimal mediumterm production schedule is presented. The main objective of this paper is to develop, implement, and verify a mathematical programming framework for the optimal mediumterm openpit mine production
Design of Surface Mine Haulage Roads – A Manual By Walter W. Kaufman and James C. Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions.
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Limited with a 20 % interest. Openpit and underground gold and silver production ceased in April 1998 and the reclamation phase took about three years.

Openpit mining is to be considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners health, as well as damage to the ecological land. Openpit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths.
