With the increasing improvement of national ecological standards, eco-environmental problems caused by super thick coal seam mining in western China are becoming more and serious. The failure law weak overburden stratum is an important factor affecting safe coal. characteristics weakly cemented under high-intensity area were studied. For this purpose, a case study was conducted 1101 working fac...

Originated from Bayesian statistics, Bayesian network,with such characteristics as its unique expression form of uncertainty knowledge, rich probabilistic expression abilities, and the incremental learning method for comprehensive priori knowledge,indicates the probability distributions and causal relations of objects, becoming one of the most striking focus among numerous current data mining m...

Association rule mining has a great importance in data mining. Apriori is the key algorithm in association rule mining. Many approaches are proposed in past to improve Apriori but the core concept of the algorithm is same i.e. support and confidence of itemsets and previous studies finds that classical Apriori is inefficient due to many scans on database. In this paper, we are proposing an algo...

In the context of open-pit mine planning, uncertainties including commodity price would significantly affect the technical and financial aspects of mining projects. A mine planning that takes place regardless of the uncertainty in price just develops an optimized plan at the starting time of the mining operation. Given the price change over the life of mine, which is quite certain, optimality o...

The paper is concerned with the hydrogeological appraisal of the proposed mining operations in theThar lignite field in Sindh, Pakistan. The Thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. In the Thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and m...

In order to study the andesitic porphyrite failure rule of open-cut blasting in diversion tunnel reservoir, taking Qianping reservoir project as an example through test and vibration detection, field observation, statistical analysis numerical simulation, technology open cut is studied. Finite element method software ANSYS was used establish finite calculation model reservoir. The process simul...

The objective of this paper is to describe the implementation of text mining grid services for Aîuri Project, which is a framework that includes a friendly user interface, data and text mining tasks, database access and a visualization tool integrated with various grid environments. The focus is the development and test of components for analysis and evaluation of unstructured data into distinc...
