The side of the square is 150 m long. The boreholes are X, Y, Z respectively. The boreholes meet the coal seam at 15 m in X, 45 m in Y, and 60 m in Z. (a) Determine the attitude of the coal seam. (b) Fourth borehole is proposed at P, the NE corner of the square land. Calculate at what depth, the borehole encounters the coal seam.

23/01/2020Therefore, geologists have long assumed that coal is a form of peat created by the heat and pressure of deep burial. The geologic process of turning peat into coal is called coalification. Coal beds are much, much larger than peat bogs, some of the tens of meters in thickness, and they occur all over the world.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The high-ash coal occurs as a number of gently dipping seams interbedded with sand and clay of the Polda Formation, and is confined to a narrow east–west-trending basin, 2–4 km wide and 15 km long. Cumulative coal thickness is generally 5–15 m and usually occurs beneath 50–130 m of Tertiary and Quaternary sand, clay and gravel.
