This document provides information about the Mahadeopuri mine located in Pench Area, Chhindwara, Madhya Pradesh. It summarizes that the mine uses two inclines for haulage and traveling, produces 250 tons of coal per day transported to a nearby power station, and is currently mining the II (A+B) seam. The mine works using the board and pillar method with a panel system in the 21D section. Details are provided about the geology, workings, haulage system, drilling, blasting, and support rules of the mine.

12. SYSTEMATIC SUPPORT RULES (SSR)
1 SSR under regulation 108 of the coal mines regulation 1957 for development working
2 This is based on the RMR of roof rock of Seam
3 The roof shall be supported by full column ground roof bolts with resin installed at maximum interval of 1.0m in the same
row(four bolts in a row)
4 The distance between the bolts and the side pillar shall not be more than 0.6m
5 Spacing between the two rows shall not be more than 1.0m
6 The bolts in a row shall be strengthened by used of W strap/steel channels of suitable specification if required.
7 Junction shall be supported by rows of bolts as specified for those of development working within 10m
8 The junction shall be reduced to 0.75m in case of resin grouted bolts and 0.65m in case of cement grouted bolts to
accommodate 25% extra support.
9 Vertical props at intervals not exceeding 1.2m with suitable laggings put tightly against the side of pillar.
10 The props may be set in recesses in floor and roof close to the side.
11 All faults, visible slips, breaks and other geological disturbances in the roof shall be supported by cogs at intervals of
2.4m on either side of such disturbances and with crossbars across there a interval not exceeding 1.2m
