Abstract: Ground efficient construction techniques of coalbed methane has multi-effect on resources, security and environmental protection. In the coal mining area, exploration and utilization of CBM is beneficial for economy, safety and environment protection. Based on geological condition characteristics of CBM development of coal 15 in Qinshui basin, the U-shape well development project was put forward, which sucessfully guide the first multilateral U-shape well construct. As a result the stimulation increase the output to more than 2.0×10⁴ cubic metres gas per day, and also provides a new way for the CBM ground efficient development of coal 15 in this area.This study introduced the general situation, well structure design, construction technology and well completion of test well group, which is important to the same type well group construction.
