Abstract

Roof bolting is the primary method of rood support in the freshly exposed roof in Indian coal mines. This practice has rapidly gained prominence in stature as a primary ingredient of roof management scheme in place of traditional timber/steel supports because of its economic and socio-ecological considerations. The timber availability has become scarce and it is also highly costly. Conventional steel supports are very costly and less manoeuvrable. Thus, roof bolting is a leading roof controlling system. A study was conducted in Indian coal mines regarding roof bolting as a major reinforcing measure. The objectives of this study were to formulate a nomogram and develop a computer software for the selection of an optimum roof bolting system for bord-and pillar development roadways of Indian underground coal mines. In this paper, formulation of nomogram is briefly explained and use of software in a case study is discussed.
