1. Scope
This standard guide covers the use of coal combustion products (CCPs) for underground mine fill applications, for the purpose of controlling mine subsidence or for the remediation of acid mine drainage. It does not apply to surface mine applications. There are many important differences in physical and chemical characteristics that exist among the various types of CCPs available for use in underground minefill. Due to physical and chemical characteristics, CCPs commonly used in mine fill applications are fly ash, flue gas desulfurization (FGD) material, and fluidized bed combustion (FBC) fly ash. CCPs proposed for each project must be investigated thoroughly to identify the appropriate mix proportions to meet the project objectives. This guide provides procedures for consideration of engineering, economic, and environmental factors in the development of such applications.
It will be used for beneficial use.
