Coal and gas outbursts are a potentially fatal hazard that must be managed when mining gassy coal seams. Mining-induced stress plays an important role in outbursts, while elastic potential is accumulated to provide energy for outburst. In this study, large-scale true triaxial (LSTT) apparatus was developed conduct experiments understand the outburst mechanism mining-induced geo-stress evolution...

based on a meta-theoretical analysis of voting, the present paper is an attempt to present a theoretical model encompassing all the possible aspects of voting in an election action system, proposing four sub-systems of voting as follows: economic voting, political voting, cultural voting and moral voting. having distinguished among these sub-systems, the writer describes the constitutive elemen...

Recent advances in functional brain imaging enable identication of active areas of a brain performing a certain function. Induction of logical formulas describing relations between brain areas and brain functions from functional brain images is a category of data mining. It is di cult, however, to apply conventional mining techniques to functional brain images due to several reasons, such as th...

one of the most important issues related to knowledge discovery is the field of comment mining. opinion mining is a tool through which the opinions of people who comment about a specific issue can be evaluated in order to achieve some interesting results. this is a subset of data mining. opinion mining can be improved using the data mining algorithms. one of the important parts of opinion minin...

one of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. after choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. choosing a mining method depends on the geological and geometrical c...

Action repetition counting is to estimate the occurrence times of repetitive motion in one action, which a relatively new, significant, but challenging problem. To solve this problem, we propose new method superior traditional ways two aspects, without preprocessing and applicable for arbitrary periodicity actions. Without preprocessing, proposed model makes our scheme convenient real applicati...

The article is devoted to the substantiation of line action for reclamationof disturbed lands. object reclamation a land plot (Russia, Leningrad Region), as result unauthorized open-pit mining operations extraction limestone. In order obtain information necessary justify project, following works were carried out: reconnaissance and route observations, topographic, geological, environmental surv...
