In order to further strengthen the prevention and control of coal gas outburst in Xinjing Coal Mine, online comprehensive analysis early warning index system rules suitable for Mine were studied. Based on corresponding computer guarantee mechanism, a outbursts was established, realizing real-time intelligent dangers working faces. The realizes standardization dynamic management information at f...

The article describes the development and application of a new discrete time-event simulation modeling methodology used in the copper mining industry in Chile. The proposed methodology creates a simulation model that represents a mine-mill operation, and it is used to evaluate different improvement options to maximize the system performance. Two applications of this methodology to existing copp...

The volumes of information developing at a remarkable rate and enormous information mining and learning revelation have turn into another test. Unpleasant set hypothesis for information securing has been effectively connected in information mining. The as of late presented MapReduce procedure has gotten much consideration from both academic group and industry for its appropriateness in huge inf...

BACKGROUND Tremolite contamination has been proposed as the cause of mesothelioma in workers exposed to commercial chrysotile. The asbestos industry and scientists it has sponsored, for example, have argued that commercial chrysotile does not cause peritoneal mesothelioma. METHOD Case report of peritoneal mesothelioma in a mill worker from a tremolite free Canadian mine. RESULTS Reports fro...

We study an extension of the precedence constrained knapsack problem where the knapsack can be filled in multiple periods. This problem is known in the mining industry as the open-pit mine production scheduling problem. We present a new algorithm for solving the LP relaxation of this problem and an LP-based heuristic to obtain feasible solutions. Computational experiments show that we can solve...

This paper outlines the status of Australian coal mining industry with respect to safety and welfare of the mine employee. The impact of tie longer shift hours and compressed working week are discussed in relation to workers safety and employment levels. Longer shift hours and compressed works have shown to be a benefit to miners, both in safety and socially. The paper also examines the role of...

Short-term production plans are the basis for operational mine production schedules. They concentrate on making long-term mine plans operationally feasible. Furthermore, some variables such as ore grade and tonnage govern mine production systems and cause uncertainty in the supply of raw materials to the mills. Due to the quality variation of material, short-term production optimization is an u...

In this paper I examine the case of the highly controversial Jabiluka uranium mine which was recently given the green signal by the John Howard government. The mine, to be constructed in the heart of the Kakadu National Park (home to the Mirrar people and a World Heritage site) has been the topic of public debate and controversy involving Aboriginal communities, political parties, the mining in...
