     The paper has studied tectonic dynamical conditions, thermal dynamical conditions and hydraulic condi- tions influencing coalbed methane enrichment in Qinshui basin. Coalbed methane enrichment units have been di- vided based on tectonic dynamical conditions in Qinshui basin and combined with thermal dynamical conditions and hydraulic conditions. The results show that there are four geological tectonic units and nine coalbed methane enrichment units in Qinshui basin, the two more favorable areas and three favorable areas of coalbed methane ex- ploitation have been affirmed by possible recovery assessment. Coalbed methane enrichment has resulted from combined action of tectonic dynamical conditions, thermal dynamical conditions and hydraulic conditions as well as time-space configuration, the reasonable combination of tectonic dynamical conditions, thermal dynamical con- ditions and hydraulic conditions could have formed the best zone for coalbed methane exploitation.
