Abstract In this paper, a large number of primary structure coal and rock in Qinnan and Edong coal mines are selected. Fracturing filtration experiments are carried out by improved filter equipment, real-time observation of filtration phenomenon, measurement of filtration related parameters, qualitative and quantitative analysis of filtration effect. The experimental results show that under the same pumping pressure, the filtration performance of coal and rock varies greatly, and the filtration performance of Qinnan coal and rock is greater than that of Edong coal and rock. By comparing the fracture development characteristics of coal and rock, it is found that the filtration of coal and rock is largely affected by the fracture development characteristics of coal and rock joints. As a fractured reservoir, coal reservoir must take reasonable and effective measures to reduce filtration performance in fractured zone, which provides a theoretical basis for further exploration and development of coalbed methane.
