Moisture content under coal reservoire condition-study onthe determinnation method of balance moisture

Abstract：Based on the experiments for the water and K₂SO₄saturation solution, grain size, time and some other things.on tne balance moisture, the causes of the influences of various factors on the balance moisture content are analyzed.Meanwhile, based on testing a lot of sampies, the technical parameters of determination method of balance moisture are modified and the optimal conditions of experiment are detemined. It has provided the accurate and reliable guarantee for the isothermal adsorption experiment. The corresponding test parameters and error range are presented.
