Researchers at the National Institute for Occupational Safety and Health studied mining accidents that involved a worker entangled in, struck by, or in contact with machinery or equipment in motion. The motivation for this study came from the large number of severe accidents, i.e. accidents resulting in a fatality or permanent disability, that are occurring despite available interventions. Acci...

This paper describes a visual interactive simulation system of technological processes intended for the development and execution of simulation and emulation models for automated process control systems in coal mining. A set of simulation models of various subsystems of a mine was developed with the help of this simulation system. These models united to create simulation environment. Simulation...

This paper presents an approach for representing and analyzing random motions and hazardous events in a simulated three-dimensional workplace, providing designers and analysts with a new technique for evaluating operator-machine interaction hazards in virtual environments. Technical data in this paper is based upon a project striving to reduce workers’ risks from being hit by underground mining...

Operation of underground coal mine mobile equipment is usually done in a restricted workspace with reduced visibility. This work environment puts machine operators in awkward postures for tasks that require awareness of their surroundings and fast reactions to avoid hazardous situations. Using experienced equipment operators as a source, researchers conducted an investigation that developed a m...

Reliability estimation plays a significant role in the performance assessment of mining equipment, and aids in designing efficient and effective preventive maintenance strategies. Continuous and random/irregular occurrence of failures in a system could be the main cause for performance drop of machinery. The accomplishment of a projected level of production is possible only by an efficient oper...

Decisions in the current and future mining environment are increasingly tied to reducing operating costs. Improving performance, productivity and profitability is crucial. Production, ancillary, plant and shipping equipment need to be monitored and controlled by online systems delivering production statistics and real-time information. Traditional systems currently in use today, operate in an i...

In view of the insufficient characteristics and depth acquisition difficulties encountered in process uniocular vision measurement, posture measurement scheme tunneling equipment based on was proposed this study. The positioning coal mine monocular to extract environmental features match features, RANSAC algorithm used eliminate pair mismatching points. This done solve optimized matching realiz...

The article analyzes the place of China in world market mining resources. It is shown that not only a leading producer metallurgy resources, but also plays unique role as world's main importer such global industry has high concentration, so no more than ten countries export metallurgical resources to China. occupies significant equipment for industry. In last decade, country become one exporter...
