With this model, it is proposed to develop a route map for modernization of regional coal mining industry, which should create conditions for the coal industry to change over from being a donor to becoming a driver of economics in the Kemerovo region. At the same time, this will enable ...
Taking CECB with three mining roadways (MRs) as an example, the concept map and specific procedures are presented in Figs. 1 and 2, respectively. Fig. 1 Conceptual diagram of using CECB for DCS and WPCM Full size image Fig. 2 Production processes of DCS Full size image First, the enti...
Corporate social responsibility (CSR) in mining areas has increased momentum especially in countries like India where it has been made mandatory. The primary objective of this paper is to document actual social challenges of mining in field areas and find out how companies in the coal sector can...
Ohio Coal-Mining Moves Above Ground The Columbus Dispatch The new look of Ohio coal mines By Patrick Cooley The Columbus Dispatch On a brisk October afternoon, Ed Spiker stood on a black surface in the middle of a quarry cut more than 100 feet into a hillside near Cadiz, Ohio, flanked on...
Fuel type now affects vehicle acceleration and top speed. Added use incoal liquefaction. 0.9.1: Slightly more coal is generated per world. 0.8.1: Color of the ore on the map changed. 0.1.0: Introduced See also Fuel Powering a factory with coal...
and surface mining. Presenting one of the first assessments based on satellite observations of gross forest cover loss combined with a map of forest C stocks, Harris et al.3estimated that the net C emissions from tropical deforestation between the years 2000 and 2005 amounted to 0.81 Pg C a...
MapReduce is a very important batch processing model. The core idea of MapReduce is that the data is first divided into small chunks of data, which are then processed in parallel to produce intermediate results in a distributed manner, and finally, these intermediate results are combined to ...
Afterward, a human–computer interactive interpretation was performed on the data, which was then merged with field investigation results and high-definition remote sensing images. This process obtained two periods of ecosystem type data, describing the ecosystem types of the Shendong mining area in ...
Finally, four groups of self-mining datasets were verified in the coal mine roadway environment, and the LiDAR odometry based on GICP and the LiDAR odometry fused with IMU preintegration were constructed for comparative analysis. The length error and absolute position and pose error of four groups...
