five factors to consider when choosing mining producersdec 02, 07· as far as picking mining stocks that are producers go, i have a few criteria that i look for. they are 1. management. 2. variety in metals being mined. 3. cash costs. 4.geotechnical factors queensminedesignwikigeotechnical factors influencing selection of mining methodmining method classificationchange of mining method in a mining operationthickness and orientation of mineralizationore and country rock strengthdistribution of mineralization within the orebodydepth of mineralization and surface conditionsgeotechnical environmentgeotechnical factors of underground mining methodssummarythe depth of the mineralization and surface conditions are the main considerations when choosing between an open pit and underground mining method. as a brief discussion of open pit mining, the ore deposit must be shallow enough to maintain an economic ore grade with construction of the pit walls. the angle of the pit walls is controlled by the strength and stability of the rockmass. in general, a less stable rockmass requires a shallower pit slope angle, while a more stable rock enables steeper slope angles t criteria for selecting a viable dmaic projectthe total score will fall into one of three possible categories less than 2.0 the project is not a viable dmaic project; it may be better to use another approach. 2.0 3.0 this is a possible dmaic project; it will require further validation. greater than 3.0 this is a viable dmaic project. some questions to which the answer is amodels for mining equipment selectionconstraints of the mining operations to a level that is acceptable and used by mining engineers. martin consultants (martin et al. 82) list the selection considerations for a truck as follows material characteristics of the mine loading equipment haul route requirements maneuvering space dumping conditions capacityiso 9001 calibration explained technical articlesoct 23, · the mandatory requirements for the iso 9001 certified companies to calibrate their instruments from the laboratories that are accredited to iso standard 025. the iso 025 provides the guideline for a calibration laboratory to follow. the focus is on personnel expertise, equipment selection, validity, documented procedures, and measured4. environmental issues related to road managementroads can have both positive and negative influences on people and the environment. on the positive side roads provide the opportunity of mobility and transport for people and goods. on the negative side roads occupy land resources and form barriers to animals. they can also cause adverse impacts on natural water resources and discharge areas. continue reading 4. environmental issuesunderstanding conveyor systems types, applications and2 days ago· conveyor systems selection considerations. when deciding on which conveyor system best suits your needs, a key consideration is the material is being transported. some important characteristics to consider are size, flowability, abrasiveness, corrosiveness, moisture content, and the temperature at which it must be kept.geotechnical considerations in open pit minesinclude premining investigations of ground conditions*, development of a mine plan and design according to the assessed ground conditions* and required rates of production etc .. once mining is underway, a system of ground performance monitoring and reassessment of mine designs should be undertaken such that the safe operation of open pits can be
