The Methane(CH_4) called Coal Bed Methane (CBM) lies in a deep coal layer. The production method in which the injected CO_2 replaces CBM is called Enhanced Coal Bed Methane (ECBM) Recovery. Since CBM is in the state of high temperature and high pressure, its physical and chemical property is not well-known. In this report we tried to simulate ECBM at the molecular level which will contribute to develop more efficient enhancement recovery methods. To give a view of the motion of CO_2 and CH_4, we adopted molecule dynamics. Molecule dynamics method is a form of computer simulation to express the exercise of the atom with the exercise equation of the Newtonian mechanics and potential between the atom. After the calculation under the simplified condition, in which I used the Lennard-Jones potential and Verlet method, an experiential parameter of the molecule dynamics method, we discuss some characteristics of the motion of CO_2 and CH_4 in terms of their energy
