Aug 13, 2019· Upper Peninsula mine approved despite major concerns from DEQ and EPA staff, records show. A Canadian mining company plans an open-pit sulfide mine 150 feet from the Menominee River.
Mar 02, 2016· The addition of IBIS-FM support in Trimble 4D Control software 4.5 can trigger early warning detection of slope instability to improve safety for workers in open pit mines. The opportunities in radar technology play a significant role in effective project safety management in monitoring operations involving highwalls, excavated faces and ...
Assessing and Monitoring Open Pit Mine Highwalls This paper introduces various warning signs of slope instability so operators are better able to recognize hazards. The most common slope monitoring equipment and practical methods of installation are discussed as well as the limitations of these systems.
A good knowledge of the mechanism of slope failure in open-cast mines can be understood by evaluating the intrinsic and extrinsic factors and their interactions in causing slope instability, and by gathering displacement information from periodical monitoring. Surface deformations, caused by mining activities at mine sites, are conventionally measured by using survey instruments such as levels ...

Top Of The Pit Highwalls If the geological formation permits, pre-splitting should be made a part of the mining method for final walls to reduce the potential for loose rock along the face. If a quarry has an exceptionally high face height, and if pre-splitting is a viable option, consider pre-splitting every shot. This is a
The Ok Tedi Open Pit Mine is located at the head-waters of the Ok Tedi River, in the Star Mountains of the Western Province of Papua New Guinea (see Figure 1). Daily rainfall records in the project area are available from 1985 onwards. The average rainfall in the period 1985—2010 is between 8m and 10m per annum (depending on the position of ...
Acid Mine Drainage Acid mine drainage (AMD) is a serious problem in areas that have a history of large-scale mining (especially coal, copper and hard rock mining).1 The geochemical oxidation of exposed sulfides on the open pit mine high walls and benches generates sulfuric acid by reacting with oxygen and water (Eq.1).

Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining . List of Open-Pit Mines · Extraction · Waste · Pollutants ...
Coal and nonmetal mining used about 4.3 billion pounds of explosives and blasting agents during 2001 in the United States. A major part of this consumption was related to surface mining.

practice in open pit mines. The application of sound geotechnical engineering practice is considered to be an integral component of Part 2 of the Mines Safety and Inspection Act 1994 (MSIA). It is emphasised that this guideline is not totally inclusive of all factors concerning the application of geotechnical engineering in open pit mining.
The OPMMS® (Open Pit Mine Monitoring System) is a laser-measurement-based monitoring system, expressly designed for automatic and manual long-range profiling of open pits' slopes and surfaces and other mining applications, specifically customized for different terrestrial laser scanners as Teledyne-Optech ILRIS or the RIEGL VZ Series.
Slope failures in large surface open-pit mines represent a major challenge for the safety of mine operators and machinery which require long-term solutions. According to NIOSH (the US National Institute for Occupational Safety and Health), slope failure accidents were responsible for 12% of U.S. surface mine fatalities and machinery damage from ...
