Abstract:
With the complex geological conditions of CBM in China, it's particularly important to select suitable development method of CBM in different areas. According to the study of the geological conditions of CBM development in Luling coal district, the main results are as follow:the geological conditions of CBM development in Luling coal district are complex. Great number of target seams have been developed, thick and have stable distribution. The coal seams are mainly tectonic soft coal, high in gas content, poor in permeability. Through analysis of the adaptability to different CBM development modes and in combination of CBM development conditions in Luling mine as well as under the present economic and technical conditions, vertical wells are the way of first choice for CBM development in the area.
