The purpose of this study was to quantitatively assess the importance of employing best practices in project planning and scheduling on capital projects’ success in Botswana, using a mining company’s strategy-critical projects as a case study. Seventy-two (72) respondents who are employees of the mining company completed the questionnaire. The study purposefully selected a convenient sample of individuals involved in managing capital projects. Data was collected using a closed-ended questionnair...

Mineral coal presents a historical chronology to society, mainly regarding energy generation, and is outstanding in relation to oil when the subject is electricity generation, besides being utilized in the cosmetics and coal gas industry. Thus, the production chain that uses mineral coal must be validated for quality, considering specific prerequisites that show the positivity of this analysis. For this purpose, the present study was characterized by a Systematic Literature Review (SLR), aiming ...

The problem of extracting surface crack information in mining area is studied. The unmanned aerial vehicle (UAV) image is used as the data source for multi-scale segmentation. The rule set is constructed based on the spectral and shape features of surface cracks. The object-oriented extraction of crack information is carried out by using the principle of fuzzy classification, and the surface crack information in mining area is successfully extracted. The extraction accuracy of surface cracks is ...

In order to solve the
difficulty of the arrangement of ore production at each mine site during the
transition from open pit to underground mining in Shirengou iron mine. Taking
the largest amount of mining as the objective function, each deposit storage capacity,
ore dilution rate, ore loss rate and grade as the constraints, thus the linear
programming model was established and solved by lingo ...

Wells performance is
evaluated by IPR curves that show the relationship between bottomhole pressure
and inflow rate. This curve and its outcome equation can be applied for production schedule and maintenance management
of well and reservoir. But, the measuring of bottomhole pressure to approach
these curves needs much time and high expenses and also running special tools
in wells. In these operations, the probability of catastroph ...

The accident data used in this paper are all collected from the traffic accident investigation team of Shanghai University of Engineering Science from 2008 to 2017. The analysis is based on full and detailed data. The conclusion can provide a reliable basis for the prevention of car accidents in domestic intersections. The content of this paper can be summarized as follows: The fault tree analysis method is used to analyze the tra ...

The oil and gas industry needs fast and simple
techniques of forecasting oil and gas production. Forecasting production from
unconventional, low permeability reservoirs is particularly challenging. As a
contribution to the continuing efforts of finding solutions to this problem,
this paper studies the use of a statistical, data-driven method of forecasting
production from liquid-rich shale (LRS) reservoirs called the Principal
C ...

Strategic environmental assessment (SEA) process can be broadly defined as a study of the impacts of a proposed project, plan, project, policy or legislative action on the environment and sustainability. SEA process has been aimed to incorporate environmental and sustainability factors into mining and mineral (MM) project planning and decision making (MMPPDM) process. Sustainable MM development is a kind ...

Mine tailings (MT) have been used in previous studies as substitute
construction material to recycle waste products, especially in hollow blocks
and bricks production and as masonry mortar. This study investigated the use of
Philex copper-gold mine tailings (PCGMT) in roller compacted concrete (RCC) production,
a mining waste material consisting of finely grinded siliceous particles was obtained
from Tailings Pond number 2 (TP2) of a Philippine copper and gold mining
company. A comprehensive exp...

Equipment failures and associated maintenance have an impact on the
profitability of mines. Implementing maintenance at suitable time intervals can
save money and improve the reliability and maintainability of mining equipment.
This paper discusses aspects of maintainability prediction for mining
machinery. For this purpose, a software tool, called GenRel, is developed. In
GenRel, it is assumed that failures of mining equipment caused by an array of
factors follow the biological evolution proces...
