Since longwall mining consists of three major machines, shearer, AFC, and shields, there are two types of "automation", "automation" for each machine and "automation" for the longwall system (i.e. the three machines operate automatically for coal production).
Abstract: Cloud computing is rapidly becoming a widespread alternative to costly on-premise infrastructures for delivering computing services in general and specifically for Data Mining services. Bearing this in mind, it is fairly convenient, to propose an architecture for the deployment of Data Mining services that would allow the underlying computing platform to be abstracted, …

Innovation plays a critical role in the mining industry as a tool to improve the efficiency of its processes, to reduce costs, but also to meet the increasing social and environmental concerns among communities and authorities. Technological progress has also been crucial to allow the exploitation of new deposits in more complex scenarios: lower ore …
The higher costs and increased risk that often arise from a prolonged permitting process can cut the expected value of a mine in half before production even begins. The combined impact of …
Miners are seeking to cut costs incurred to produce mining output, or to increase output at no additional cost—in other words, to raise productivity. CEOs have been acknowledging to …
Present study works on identification of causes of delay in mining/manufacturing projects in Indian context. An approach is suggested to carry out ranking of these causes by two different …
The analytic procedures incorporated to facilitate the delivery of projects are often referred to as project analytics. Existing techniques focus on retrospective reporting and understanding the ...
Modelling. In this step, various machine learning techniques were used to develop predictive models. Logistic Regression, Neural Network, Naive Bayes, Random Forest and Decision …
4.7. Data description and pre-processing. Before describing the data, the first task to be done is data pre-processing. In fact, an important issue when processing agency data, as pointed out in Barbeau (2018), is its accuracy, as some agencies might fill in some data with random values just to fill the gap instead of providing missing values.In this experiment, we …
