Geotechnical Rationale and Scope for Flyash and Side Bolts as Altenatives to Sand in Pillar Reduction and Stabilization

ABSTRACT

The paper examines the feasibility of using flyash in conjunction with side bolting as a substitute of sand filling. The geo-technical rationale of such an approach and its applicability in different Indian Coalfields have been discussed.
