A composite cavity-forming technique is developed, which includes a set of safe and highly effective jets plus mechanical tools based on the fact that the efficiency is universally low and risks are high in making cavities in open CBM wells both at home and abroad. After making site tests in a multiple of wells, the authors developed a series of jets and mechanical tools and the associated cavity - making technology. Breakthrough was made in a number of technologies, which provide technical guarantee for effective extraction of coalbed methane.
