"The methodology describes the preparation of grain polished sections of coal in order to achieve the most accurate results when measuring the contact angle. The values of contact angle are affected by the properties of coal (petrographic composition, degree of coalification, ash content) and in their own way of the sample preparation when using method (sessile drop method) with the placement of water drop on the mineral surface. In the methodology influences of various factors on the accuracy of results were investigated. Based on statistical evaluation of grain samples the smallest number of measurements that must be made to ensure adequate accuracy was determined, so the deviation was less than 1\u00B0."@en .
