Geological Study in Miike Coal Field by Sonic Exploration (2nd Report)

Deformation of Coal Induced by Methane Adsorption at Geological Conditions

The quenched solid density functional theory (QSDFT) is employed to study methane adsorption on coal at geological conditions. Themain focus is made on coal deformation in the course of adsorption that may result in either expansion/swelling or contraction, depending upon the pressure, temperature, and pore size. Twoqualitatively different types of deformation behaviorwere found depending upon ...

Study on 3d Modeling and Visualization in Geological Exploration Engineering

With the development of GIS, its applications concern with different domains, such as geography, mapping, urban, traffic, geology, mine, military and so on. 3D GIS is the research hotspots in the domains of city, geology, mine etc. 3D GIS in city has been developed more quickly, CyberCity, for example is a smart application of 3D GIS, but it is slow in subsurface engineering because of its comp...

Coal Exploration and Mining

Combinatorial framework for planning in geological exploration

The paper describes combinatorial framework for planning of geological exploration for oil-gas fields. The suggested scheme of the geological exploration involves the following stages: (1) building of special 4-layer tree-like model (layer of geological exploration): productive layer, group of productive layers, oil-gas field, oil-gas region (or group of the fields); (2) generations of local de...

Geological and Geochemical Features of Alborz Basin Coal Deposits, Iran

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...
