The wide adoption of underground mining has contributed immensely to the rapid growth of the countries’ economy, job creation, gross domestic product, fixed capital formation, gross investment and merchandise exports on an enormous global scale. At the same time, the tedious and dangerous nature of underground mining makes it vulnerable to mine accidents and disasters, such as the fall of loose...

The coal and gas outburst is one of complex geological disasters and its prediction is influenced by a multiple of factors, such as coal gas, ground stress, physical and mechanical properties, and complex non-linear system, which cause the low prediction accuracy. It is a favorable scheme to use the nonlinear BP neural network for the prediction algorithm design. But, the traditional BP neural ...

The history of mining disasters includes cases of subsidence and collapse into workings, and also a number of inrushes into underground mines, where deficiencies in surveying, or in maintenance and interpretation of plans, were prime factors. The most recent incident in Australia was at the Gretley Colliery in NSW, in 1996. The most recent such incident in the USA was at the Quecreek Mine in So...

crush injury of an extremity occurs when a limb is compressed between two hard surfaces, to the point where vascular supply is impaired and vulnerable tissues undergo necrosis. most commonly, limbs are crushed during auto versus pedestrian accidents, motor vehicle crashes, and industrial accidents. however, during natural disasters such as earthquakes, buildings collapse, landslides, mine cave-...

This study developed a chatbot to improve the efficiency of government activation mine safety procedures during natural disasters. Taiwan has comprehensive governmental system dedicated responding frequent disasters, and Bureau Mines instituted clear ensure delivery disaster alarms damage reports. However, labor- time-consumption are inefficient. In this study, we propose framework for disaster...

The geological structure of coal mines has always been a dangerous object attention in mine outburst prevention work. In order to realize safety information management and early warning gas disasters, comprehensive use theory, disaster computer technology other analysis methods, considering the influence structure, seam occurrence parameters, an indicator system for identifying risk outbursts r...

In view of disasters caused by rock burst becoming more and more serious in coal mine production, three models are established for evaluation and prediction the rock burst risk based on artificial neural network. First, ten indicators are determined which have a larger influence on rock burst. Then two back propagation network models are trained using the original data and the processed data re...

Underground coal mining is a dangerous industry where the regulatory state may impose tradeoffs between productivity and safety. We recover the marginal tradeoffs using disasters near a mine as shocks that increase future accident costs. We find that in the second year after a disaster, productivity decreases 11% and accident rates decrease 18-80% for mines in the same state, with some evidence...

Background: Occupational accidents cause death and disabilities among millions of workers around the world. The mining industry is among the riskiest occupations in this respect. This study aims to investigate interventions made and challenges faced by the health system in response to the Zemestan-Yurt Mine explosion in the Golestan Province, Iran, 2017. Materials and Methods: In this article,...
