Mining is the process of extract the oreminerals from the oremineral deposits. Mining operation can done in two ways either opencast or underground process. In underground mining the extracted areas are to be back filled with incombustible materials like sand or fly ash for ensuring the safe conditions of mined area. The process of back filling the mined out aera with different filling materials is known as stowing. Stowing is practiced in depillaring stage to fill the voids with incombustible material formed during extraction of pillars. Stowing process is essential for underground working areas to avoid the subsidence, roof collapsing. In mines the stowing method can be carried out with different methods. Generally hydraulic stowing practice is widely used. In this paper an extensive study was carried on various hydraulic stowing methods and result shown that the use of pond ash as stowing material is having more benefits when compared to other materials.
