Coalbed methane is not only a valuable clean resource, but also a major hazard in coal mine safety production. The discerption of mining right leads to the contradiction between the coal enterprise and the coalbed methane enterprise, which hinders the healthy development of coal and coalbed methane industry. Based on Game Theory, this paper studies the coalbed methane cooperative mining under the discerption of mining right. The strategy set and income function of the coalbed methane enterprise and the coal enterprise are given respectively. The game model is established and solved, and the results are analyzed. The results show that the realization of coalbed methane cooperative mining relies on the ratio of income distribution and the charge to transfer right of gas mining. The influence of system parameters on the game equilibrium results is shown by numerical experiments.
