Evaluation Research on the Hydrogeology Conditions of Coal Bed Methane Row Production

Article Preview

Abstract:

This paper confirms that the mining of the coal bed methane (CBM) are most significantly influenced by the hydrogeology parameters of the reservoir itself, the hydrogeology parameters, the supply properties and the geological structure of the roof and floor and other neighboring water-bearing rocks hydraulically associated with the coal bed as well as the difficulty degree of CBM mining; a evaluation indicator system structure of the hydrogeology conditions are established based on the foresaid conclusions and the CBM mining hydrogeology conditions are divided into “beneficial, moderate and adverse” grades; this paper finally divides the threshold to grade the hydrogeology condition evaluation indicators and a complete CBM mining hydrogeology conditions evaluation indicator system is founded to evaluate the hydrogeology conditions.
