CO2 Storage and Geothermal Extraction Technology for Deep Coal Mine

Development of Drilling Technology for Deep-seated Geothermal Resources

Concept of the deep-seated geothermal resources Deep-seated geothermal resources is defined as the depth of 3000-4000m at temperature of approximately 350 degrees C. And it is considered that those deep-seated geothermal resources exist below shallow geothermal reservoirs whch already exploited. 580,000 KW. And it is indispensable to explore geothermal resources " to increase it rapidly. In Jap...

An Innovative Longwall Mining Technology in Tangshan Coal Mine, China

In mining of inclined coal seams in Tangshan coal mine of Kailuan group, gateways on either end of a panel were both typically located along the floor and a gateway pillar between adjoining panels was left unmined between adjacent panels to ensure stability, thus forming a planar mining system. According to the practice, however, it turned out that this conventional mining system has long-stand...

A Study of Mine-Related Seismicity in a Deep Longwall Coal Mine

This study involves seismic monitoring of a deep coal mine. The purpose is to examine the processes responsible for induced seismicity. A seismic network consisting of five threecomponent short-period seismometers located above the mine recorded the seismic data. The events discussed here occurred from March 1, 2009 until April 7, 2011 during the mining of three longwall panels and the data was...

Characterization for Storage of CO2 in Deep Geological Formations

The U.S. Department of Energy (DOE) is the lead Federal agency for the development and deployment of carbon sequestration technologies. As part of its mission to facilitate technology transfer and develop guidelines from lessons learned, DOE is developing a series of best practice manuals (BPMs) for carbon capture and storage (CCS). The ―Site Screening, Site Selection, and Initial Characterizat...
