There are a lot of white ore in Jixi Qingshan coal mine. Argillization of this ore is very terrible. This ore quickly turns to fine white slime in water and forms the stable suspending liquid. It leads that slime water form sediment is very terrible. This paper analyzed and researched the characters of the fine white slime water. The experiment results showed that the combined applied effect of MgCl2 and NPAM can enhance form sediment effect.

Abstract:

Coal ash is a byproduct of coal-fired power plants, and the management and disposal of coal ash in coal ash pits is an environmental health concern. Evidence suggests that socioeconomically disadvantaged communities are more likely to bear the burden of these environmental hazards. However, limited studies have investigated the relationship between socioeconomic status and residential proximity to coal ash pits. We examined associations between census tract poverty and non-white race with the likelihood of having coal ash pits within the census tract. We obtained coal ash pit location and cens

One of the possibilities of using RES, which could be used in co-firing processes with coal, is biomass obtained from fast-growing woody species, such as poplars and willows.

Abstract:

Coal is usually found in many sandstone-hosted uranium deposits in western China. However, it remains unclear whether coal organic matter is related to the mineralization of uranium in sandstone. In this study, the organic matter of coal containing lenticular carbon plant strips and carbon clastics was analyzed in different alteration zones in the Daying sandstone-hosted uranium deposit located in the northern Ordos Basin. According to geological and geochemical characters, Daying sandstone can be classified into three alteration zones: the oxidation zone, the transition zone, and the reductio

Abstract This paper reports determining the grayscale intensity of macerals in the coal lump polished sections oriented along and across the layering of three main groups of sub-bituminous, high volatile bituminous, low volatile bituminous coals. All measurements have been performed in white, red, yellow, green, blue light. The influence of all selected factors and most of their combinations on grayscale intensity is reliable; the most pronounced effects are established for the optical filter color and the maceral type. Comparative analysis of the grayscale intensity data array with the spectr

Studies carried out to investigate the effect of slow release nitrogenous fertilizers with different levels of nitrogen (N) on mahagement of rice pests. indicated that application of prilled urea with need based plant protection recorded less population of green leafhopper (GLH) and less percentage of gall fly damage as well as stem borer white ears. Neem blended urea (5:1) also recorded less population of GLH and earhead bug. Coal tar coated urea registered less white ears due to stem borer. Increased doses of nitrogen from 75 to 150 kg/ha was found to increase the population/damage of above

Abstract:

Coal is the most abundant fossil fuel resource, acting as a terrestrial carbon sink since the evolution of forests in the Late Devonian. Debate concerning its accumulation began centuries ago when naturalists ascribed its formation to catastrophism associated with the Genesis Flood. With empirical data derived from both modern peat accumulations and ancient coal deposits in the mid-to-late 19thCentury, the general scientific community developed a set of criteria upon which to demonstrate the autochthonous (in situ) nature of most peat accumulations. At the same time, adherents to the teachings

Abstract:

Despite its pivotal economic position in Central Africa, the history of Zimbabwe's Wankie Colliery has scarcely been explored. Although the historical pattern of capital accumulation and class struggle on the colliery has yet to be traced in any detail, this article suggests that a useful starting point is the protracted labour crisis which convulsed the colliery in 1918. Attempts to expand output through intensified pressure on a dwindling supply of black labour soon established a vicious circle in which workers' health deteriorated rapidly. Hundreds of black miners were incapacitated by ‘tro

Abstract:

Environmental management of ex-coal mining land needs to be carried out through reclamation activities. Revegetation is an effort to repair and restore damaged vegetation through planting and plant maintenance activities. In this regard, it is necessary to assess the achievement of the reclamation activities that have been carried out as an effort to review the return of ex-coal mining land to its original habitat so that restoration of ex-coal mining land can be effective and efficiently implemented in the field. The purpose of the study was to determine the percentage of plant life and the l
