During the course of deep coalbed gas exploitation, the ceramic proppant with a good mechanical structure and flow conductivity are benefited to improve the mining efficiency of coalbed gas. Reprocessing of proppant raw materials is conducive to obtaining superior properties to meet the application in complex stratigraphy environment. In this paper, ceramic proppant for coalbed gas exploitation was prepared by using stale treatment on the low-grade bauxite and solid waste of coal gangue. The effect between the water wettability and sintering property was analyzed with the different stale interval. The variation rules of stale hydration were investigated on proppant about the microstructure density, pore distribution and phase size. Finally, the high-quality ceramic proppant was synthesized for satisfying the demand of coalbed gas mining, which provides the research basis for the efficient utilization of mineral resources and the stable exploitation of coalbed gas in the future.
