PURPOSE The purpose of this study was to test whether population mortality rates from heart, respiratory and kidney disease were higher as a function of levels of Appalachian coal mining after control for other disease risk factors. METHODS The study investigated county-level, age-adjusted mortality rates for the years 2000-2004 for heart, respiratory and kidney disease in relation to tons of...

A gas coal (B) was used to study the effect of volatiles on sulfur removal from a high organic-sulfur coking (A) perspective mass transfer conditions. The driving force and resistance were analyzed in terms fluidity development, permeability plastic stage flow, volatile matter release. Carbonization using vertical horizontal stacking modes two coals designed according release directions during ...

To facilitate predictions of the transport and fate of contaminants at future coal conversion facilities, rates of microbial transformation of polycyclic aromatic hydrocarbons were measured in stream water and sediment samples collected in the vicinity of a coal-coking treated wastewater discharge from November 1977 through August 1979. Six radiolabeled polycyclic aromatic hydrocarbons were inc...

Understanding of the influencing factors of industrial sector carbon dioxide emissions is essential to reduce natural and anthropogenic greenhouse gas emissions. In this paper, we applied the Logarithmic Mean Divisia Index (LMDI) decomposition method based on the extended Kaya identity to analyze the changes in industrial carbon dioxide emissions resulting from 39 industrial sectors in Inner Mo...

Precisely describing the formation and evolution rules of coal-rock fracturing crack have great value on reservoir fracturing improvement and highly efficient mining of coal bed methane well. In this paper, a non-linear dynamic method is used to study crack damage evolution behavior of coal-rock fracturing. Considering distribution characteristics of natural cracks in coal-rock, and based on da...

This paper uses nonparametric causality-in-quantiles tests to examine the asymmetric effects of climate risk perception (CRP) on thermal and coking coal futures high-frequency returns volatilities. The results show that CRP significantly impacts dynamic market, with volatility indicators exhibiting asymmetry at different percentiles being more pronounced in a downward market. influence mainly t...

In this study, the in situ compressive strength of iron coke high-temperature carbonization was investigated. The strengths briquettes with 20, 30, and 40% ore at 700, 800, 900, 1000°C for 3 h were systematically studied. mass loss microstructure during also results showed that increased content from 20 to 40%. liquid phase slag calculated using FactSage software. Results an increasing temperat...

Disabilities of coal miners due to black-lung decease morbidities are rather high (up to 10 men per 1 million tons of mined coal). Besides that, dangerous to health biological activity is also proper to various carbon nanoparticles. The analysis of relationships between coal miner morbidities, biological activities of coals and bibliographical data has shown that: activity of coals is mainly de...
