Abstract: Economic development as well as realisation of the basic human needs is becoming increasingly dependent on the availability of modern energy availability. Fossil fuel based energy still remains the major source for sustaining and improving standard of life though there are strong strides made by other sources as hydro, nuclear, gas, oil, etc. One estimate put the proven coal reserve in the state of Illinois to be at least 30 billion tones, another puts it 80 billion tones. Coal production from the mines in Illinois contributed about 61.7 million tons in 1990. In mines pillars are left to perform a variety of functions which influence their size and disposition. Room and pillar method of coal mining constitute the major mechanism of coal extraction in most parts of the world. Wilson’s approach divides the pillar into two zones and approximate rules were prescribed for stresses in the two zones. Partial extraction of coal through room-and-pillar mining mechanism plays a major role in Sp...
