In 2007, the Department of Industrial Engineering at the University of Chile allied with a major Chilean mining company to inaugurate a master’s degree program in globalization management. The program’s objective is to address the challenges Chile faces in its development of human and social capital by training young professionals. This paper describes the use of mathematical programming models...

The working face is the most dangerous place of coal mines, and it difficult (even impossible) to replenish energy by replacing batteries sensor nodes in faces. This paper presents a wireless charging method for this scenario that composed two sub methods called mining maintaining charging, respectively. Mining provides opportunistic services during process cutting through airborne Mobile Charg...

Forensic Image Databases appear in a wide variety. The oldest computer database is with fingerprints. Other examples of databases are shoeprints, handwriting, cartridge cases, toolmarks drugs tablets and faces. In these databases searches are conducted on shape, color and other forensic features. There exist a wide variety of methods for searching in images in these databases. The result will b...

Under the guidance of green mining and scientific ideas, strata movement its control have achieved a series research developments in China. Based on summary achievements related to characteristics, influences activity surface environment, utilizing controlling methods, critical problems that need be solved are identified for study control. Mining activities will cause redistribution stress. The...

Rib spalling disaster at the coal mining faces severely restricted safe and efficient output of resources. In order to solve this problem, based on analysis current status rib in three-soft seam 1508 Working Face Heyang Coal Mine, a mechanical model sliding-type was established main influencing factors that affect are given. The mechanism grouting technology prevent control has been theoretical...

During the mining process of fully-mechanized caving faces, roof roadway behind working face easily forms an arched-shape hanging structure with pushed forward, which results in potential hazards such as gas accumulation and large-scale collapse. Based on actual situation a at difficult end top coal through borehole exploration, surrounding rock displacement observation, bolt stress monitoring,...

We present a novel strategy for deriving a classification system of functional neuroimaging paradigms that relies on hierarchical clustering of experiments archived in the BrainMap database. The goal of our proof-of-concept application was to examine the underlying neural architecture of the face perception literature from a meta-analytic perspective, as these studies include a wide range of ta...

Green mining plays a vital role in achieving environmentally friendly and ecologically sound practices. In domestic areas, the coal method is gradually transitioning from collapse to filling mining. Paste has been proven effective controlling surface deformation, although understanding of its underlying control mechanisms remains incomplete. This study focuses on E1302 paste-filling working fac...

industrial-scale r&d it projects depend on many sub-technologies which need to be understood and have their risks analysed before the project can begin for their success. when planning such an industrial-scale project, the list of technologies and the associations of these technologies with each other is often complex and form a network. discovery of this network of technologies is time con...
