The existing technical problems Challenging the Development and utilization of Coalbed Methane in Henan 1) The complicated geological structure thatcaused the greatly unbalanced distribution of coalbed methane; 2) The great difficulty of coalbed methane drainage;. 3) The urgent improvement of the coalbed methane drainage equipments 4) The lacking of fund input; 5) The lagging of management construction which hinders the comprehensive utilizing of coal mine methane.#164 The future development and utilization of coalbed methane in Henan, China It is an urgent task to adjust China's energy consumption structure so as to meet the high demands on energy and to face challenge of energy security. The total resource amount of Henan is 879.571 billion cubic meters with overburden depth less than 2000m, the development and utilization of the methane source would be great contributions to energy security in China#17Thank You!
