The results show that the methane drainage quantity from the bores perpendicular to face cleat was 1.2 times that of the bores parallel to face cleat in any time and the difference between them becomes more distinct with the drainage time increasing. In the research area, the bores perpendicular to the face cleat was 2.61 times that of the bores parallel to face cleat in maximum drainage quantity and 4.34 times that in drainage effect, and the reasonable time is about 300 days.

The literature values of methane solubility in hexane at temperatures of 298.15 K, 303.15 K and pressures up to 12.0 MPa validated the precision and stability of the apparatus. The total deviation of the system was less than 2.5﹪. The method of fitting gas solubility at high pressure by Krichevsky-Kasarnovsky K-K equation was also proposed and corrected.
