Discussion on Surface Exploitation and Utilization Trend of Coalbed Methane

In this paper，the exploitation and utilization status of coalbed methane resources at home and abroad were introduced，and the analysis showed that the focus of coalbed methane exploitation at the stage of“13^thFive－Year”Plan in our country should be surface coalbed methane exploitation．Based on the requirements of the geological conditions of coal seams and coal mining，the permeability enhancement technology by fracturing and the surface coalbed methane extraction technology in coal mining area were described，the policy and economic issues faced by surface coalbed methane exploitation were analyzed，and corresponding suggestions were put forward．The paper also introduced the surface coalbed methane utilization ways，and it pointed out that the coalbed methane utilization projects should select proper utilization ways according to the gathering and transportation conditions，the size and composition of gas sources．it was concluded from the analysis on the surface coalbed methane exploitation and utilization that the exploitation and utilization of the surface coalbed methane had positive significance for the improvement of the coalbed methane utilization efficiency，and was the development direction of coalbed methane exploitation and utilization in the future．
