A 15m wide and 15m high 30m long underground storage facility is excavated in a massive limestone rock mass (with few random long joints). The long axis of the excavation is oriented N50°W. Traces of two major joint sets are identified as following: Joint A: plunge of trace of the joint on east wall is 29°S; trend of the line of intersection of the joint on the roof is 20°. Joint B: plunge of trace of the joint on east wall is 36°N; trend of the line of intersection with the roof is 286°.

Borehole A passes through a coal seam at a depth Of 50M and reaches a lower seam at a depth of 450m. Boreholes B and C reach the lower seam at depths of 150m and 250m respectively. Having determined the dip and strike, map in the outcrops of the two Seams(assume that the seams have a constant vertical separation of 400m). Indicate the areas where the upper seam is at a depth of less than 50m below the ground surface. It is necessa6to first calculate the height(relative to sea level) of the lower coal seam at each of the points A,B and C where boreholes are sited.
