Taking Renjiazhuang coal mine as the object of study, this paper carries on evaluation to destruction degree in this area by using extension theory and establishing evaluation extension model of land destruction in mining area. Results show that severe destruction area of collapse land in Renjiazhuang coal mine is 112.86hm, moderate destruction area is 372.27hm, light destruction area is 723.42...

Among all the 119 counties (cities, districts) in Shanxi province, China, there are 94 counties with coal resources, and 80% are resource-based mining cities. Since 2008, a number of small coal mines have been shut down due to the integration of coal resources in Shanxi Province, as well as merger and reorganization of large state-owned coal mining enterprises are under efficient operations. Th...

In the present study, 45 rainwater samples were collected from February to December 2012 on event basis in East Bokaro coal mining environment. Physico-chemical and major ionic compositions of rainwater samples as well as water soluble major ion composition were analyzed to employ principle component analysis for source identification. The average pH value was recorded 6.1 and varied from 5.1 t...

We used data from a survey of 16493 West Virginians merged with county-level coal production and other covariates to investigate the relations between health indicators and residential proximity to coal mining. Results of hierarchical analyses indicated that high levels of coal production were associated with worse adjusted health status and with higher rates of cardiopulmonary disease, chronic...

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 reports on an industrial application of modern signal processing technology in the development of a new automatic conveyor and bolting machine for underground coal mining. The machine is of special interest to the mining industry as it improves mine personnel safety as well as increasing the efficiency of roadway construction. We show how real-time signal processing component technol...

Coal miners are exposed to a wide range of genotoxic agents that can induce genome damage. In addition, miners are characterised by a high risk of the initiation of different occupational inflammatory as well as non-inflammatory diseases. The aim of this investigation is to analyse the modifying influence of occupational pulmonary inflammatory diseases on the level of chromosome aberrations (CA...
