CHAPTER 1: INTRODUCTION
Dorstfontein Coal Mine is situated at the northern limb of the Highveld Coalfield (Snyman, 1998). The close proximity of the Nebo Granite Suite the heights increase but the yields of the thin seam coal drop to uneconomical proportions. Stowing the parting underground is seam equipment will be introduced and tested below the parting.

helpful in coal preparation plant design. However, large-diameter cores are often expensive, hard to handle, slow to drill, and can have complex sample preparation and analysis requirements. Drop shatter Drop shatter tests are done to simulate the dry breakage of coal in mining, run-of-mine (ROM) sections, and ROM stockpiling.

A drop shatter test has also been described for determining the friability of coal (ASTM D440) which is similar to the standard method used as a shatter test for coke (ASTM D3038). In this method, a 50-lb sample of coal (2–3 in., 4.5–7.6 cm) is dropped twice from a drop-bottom box onto a steel plate 6 ft below the box.

Coal breakage and the quantity of coal lost as a result of shattering in falls from conveyors is a key consideration for coal sellers, mines, power plants, preparation plants, ports and terminals. Results from SGS drop shatter tests allow you to estimate the capacity of your coal to resist breakage during handling and transportation.
ASTM D440 Standard Test Method of Drop Shatter Test for Coal
The test method is serviceable for ascertaining the similarity of coals in respect to size stability and friability rather than for determining values within narrow limits in order to emphasize their dissimilarity.
