The subject of the paper is investigation of the properties of concurrent vibro-acoustic signal in the process of rock massif separation with the method of rotary drilling. The aim is to investigate the possibilities of using this signal as an integrating information source for the purposes of identification of the process of separation from the viewpoint of efficiency of the set mode (pressure, revolutions, and indenter) under current geotechnical conditions. Investigated is the possibility of recognition of the ...

Continually and impressive amplification of internet technologies development and implementation enables the creation of productive, efficient, rich useful and interactive web applications. The contribution briefly characterizes a SOA (Service Oriented Architecture), WS (Web Service) and AJAX (Asynchronous JavaScript And XML). The paper illustrates advantages of AJAX and WS integration on application example for interactive selection of one or more minerals according to actual chosen selection criteria. The applic...

The process of rock massif separation with the method of rotary drilling is a dominant process in geotechnology and in subterranean raw material mining. The type of drilling tool used and the mode of drilling with given properties of the rock are crucial in the determination of energy efficiency of this process. The research is directed toward classification of rocks into classes (pattern classification) according to geomechanical properties and the determination of efficient mode of drilling for individual define...
