According to van der Aalst 2 process mining techniques can be divided into three directions (1) process discovery which uses event logs to generate process models (2) conformance checking
utilization of machinery with an aim to improve the same. Different mines are following different terms and maintaining different information. The only common information in most of the mines is the working hours of shovels. There is a need to develop proper feedback and to define terms factors and indices relating to mining equipment.
Abstract— The low utilization of personal protection equipment (PPE) can cause a high rate of work accidents. The contributing factors related to PPE utilization need to be explored. This study aimed to explore the contributing factors of personal protection equipment utilization among sand and gravel mine workers. This study was crosssectional.
Jun 02 2019 · Utilization Factor = The time that a equipment is in use./ The total time that it could be in use. Example The motor may only be used for eight hours a day 50 weeks a year. The hours of operation would then be 2000 hours and the motor Utilization factor for a base of 8760 hours per year would be 2000/8760 = .
In mechanized mining poor equipment efficiency can endanger the success of the operation by increasing the total production cost (Fourie 2016). The mining equipment efficiency is measured by availability utilization and productivity (Fourie 2016). These factors of efficiency of mining equipment vary considerably as a far as

The second section describes underground mining equipment with particular focus on excavation machinery such as boomheaders coal cutters continuous miners and shearers. 1. Underground Mining Methods Classification of Underground Mining Methods
One of such factors is the availability and utilization of tools and equipment. Tools and equipment for teaching are the educational resources that are available in schools that can be used to achieve educational goals and objective (Adeogun 1999). These include workshops equipment and tools. These tools and
utilization factors were further used to adjust (reduce) the total airflow calculations for a diesel equipment fleet. However in light of the drastic reductions to diesel equipment emissions mandated by the US EPA There are many factors that influence the selection of mining equipment ( host rock strength mining method production

Jul 2 2021The above references are lack of deep mining of influencing factors so that they can not fully reflect the operation efficiency of distribution equipment under the multidimensional of grid side load side and management side. In the determination module of key influence factors the data samples of equipment utilization factor of each
availability and utilization of equipment besides ensure overall equipment effectiveness as per CMPDI norms/global bench marks. OEE shows that how an equipment is utilized with its maximum effectiveness. It uses parameters like availability performance and utilization for the estimation of equipment effectiveness.
Capacity utilization for the overall industry moved up in 2021 and early 2022. Both manufacturing and mining contributed to the rise. If you were to ask a normal person what percentage they think a manufacturing plant would need to produce in relation to its maximum. It is obvious that capacity utilization is a key factor in the company s
Falls in equipment utilization are mainly a consequence of „bottlenecks" (restrictions) failures in the provision of raw materials be used effectively to assess the efficiency of machinery and equipment in hard coal mining. 3. Process systems in underground mining Durlik 9 recognizes the basic process in a mine to be extraction

Mar 25 20211. Large Mining Trucks. To move materials around a mine site workers need heavyduty trucks. Also known as offhighway trucks large mining trucks include both powerful mechanical models and environmentally friendly electric drive models.. Unlike conventional trucks these mining vehicles have extralarge tires to support the heavy loads over uneven terrain commonly found around surface mines.
Generally the scale of operations involves the purchase of a single mining equipment that may cost several millions of dollars but as productivity increases over time the cost of operation outweighs the purchasing cost of the equipment. The equipment selection problem is often affected with a cascade of interdependent variables and parameters.
1 day agoThe key factors driving the growth of the mining automation market are increasing number of government initiatives to attract foreign investments and promoting mining automation increasing
In mining operations huge quantities of ore and waste material at mine sites are transported using extremely large equipment 24 hours a day. We focus on the latter problem increasing equipment utilization by better planning and optimal management of the equipment. Major components of material handling are trucks shovels and loaders
• The capacity of mining equipment is huge. Therefore the effect of utilization on total production is very high. • The physical environment under which mining equipment operates is less than ideal. • The operating environment of the mine is dynamic with many unknowns that can affect the equipment utilization drastically.
Nov 3 2022A Canadian company is testing mining equipment in the Pacific Ocean in its quest for metals needed for electric vehicles. Environmentalists oppose the mining which could begin in 2024.
Equipment Utilization. Fundamental Premise All equipment is available to be run 7 X 24. Unscheduled Time. Speed Loss Factor ( SLF ) = 1 250 / 300 = .167 Speed Loss Time = Remaining Time SLF Speed Loss Time = 5 .167 = .83 hours Step 3. Calculate the total time for Speed Loss Minor Stoppages.
in equipment utilization lias appeared in other industries which have been examined whether or not their capital stock is growing or declining. An average unit of generating equipment in electric utilities in the mid1950 s worked about 60 percent more hours per year than in the decade of the 192(rs. In mining exclusive of
To use this online calculator for Equipment Utilization Factor enter SE when SC fully utilized (S) Total Number of SE () and hit the calculate button. Here is how the Equipment Utilization Factor calculation can be explained with given input values > = 5/7.
The degree of equipment utilization and mechanization of a construction project clearly will have direct bearing on jobsite labor productivity. The contractual agreements play an important role in the utilization of union or nonunion labor the use of subcontractors and the degree of field supervision all of which will impact jobsite labor
For example it is estimated that utilizing smart sensors could create USD 34 billion in value for the mining industry by facilitating predictive maintenance improving equipment utilization reducing downtimes and equipment failures and lowering the frequency of health and safety incidents.

Use (or utilization) factor the ratio of the time that a piece of equipment is in use to the total time that it could be in use. For example the motor above may only be used for eight hours a day 50 weeks a year. The hours of operation would then be 2000 hours and the motor use factor for a base of 8760 hours per year would be 2000/8760
For example if a piece of equipment cost 20 000 and brings in 14 000 annually it is getting 70 utilization. Achieving optimum utilization is a balancing act.
