Through the distinguish software application along with formal calculation method the study represents a volumetric estimation of require backfill Materials of Barapukuria coal mine in north western Bangladesh, the only coal mine of the country under production, which capable of a low recovery with sustaining mining method. The only productive coal seam of the mine, Seam VI is our main focus during the assessment. Different estimation method is applied to investigate the accuracy of calculation and find out the reasons beyond the deflections. Surfer 8.4 exploits two method of interpolation, inverse distance to power, a weighted average interpolator and Kriging, more flexible gridding method, those yields the volume of 169221180.5 cubic meters and 165323770.4 cubic meters respectively. On the contrary Rockworks is estimated the volume through Delaunay Triangulation method as 115,959,398.4 cubic meters whether another estimation which is made by inverse power weighting interpolation on saved stratigraphic model, gives 174,281,203 cubic meters volume, following 185,760,000 cubic meters through geological reserve calculation. After considering the interpolation approach, available data and previous study agreement, the result of inverse distance to power, at both of software’s is consider for backfill materials volume estimation. The required volume of backfill materials is 101532708.3 m3 and for 9% and 10% recovery that’s are 9137943.747 m3 and 10153270.83 m3 respectively. The daily requirement of backfill is 562 - 636 m3 and the system need to have a daily capacity of 702 – 795 m3.
