Use of Foaming Mud Cement to Terminate Underground Coal Fires and to Control Subsidence of Burn Cavities

摘要

Foaming Mud Cement (FMC) is a class of materials related to cellular cement studied and developed for the purpose of addressing Abandoned Mine Land problems. During the 2-year program, significant advances were made using a specific methodology that properly employed will enable the successful termination of many surface and underground coal mine fires. Fundamental but key developments attained were: the ability to effectively isolate burning coal from the available air by effectively isolate burning coal from the available air by effectively penetrating burning coal rubble with heat resistive FMC and encapsulating and isolation of a wide range of coal particle sizes, resulting in permanent coal fire termination by air exclusion. The materials developed were specifically designed to terminate underground coal fires and preventing further subsidence.
