The invention relates to an adjustable belt type feeding and weighing device and method for an underground coal bunker of a coal mine, and discloses a weighing device and method which are used for preprocessing materials through vibration screening to enable the materials to be more evenly distributed on a skirt belt, then collecting speed and pressure signals to calculate feeding instantaneous flow for weighing, and guaranteeing feeding and weighing precision. The driving unit is arranged on the bottom plate and used for driving a driving roller, the driving roller is arranged on the bottom plate and used for driving a skirt belt, the supporting carrier roller is arranged on the bottom plate and used for supporting the skirt belt, a damping spring is arranged on the supporting carrier roller in a sleeving mode, and the weighing carrier roller is arranged on the bottom plate and used for weighing the skirt belt. The weighing carrier rollers are installed in the middle of the bottom plate, the three sets of we
