In April and May, the Huaibei area entered the rainy season, and the incoming coal became wet and sticky through rain and infiltration, which brought some difficulties to the storage, transportation and blending of incoming coal. In view of this situation, the WOM Pingshan Project Department has taken many measures to actively respond to the situation and overcome the difficulties caused by coal tide in rainy season on safety production.

        The Pingshan Project Department starts with compacting coal seam, sets up a mechanical team of coal yard to carry out stratified and sectional coal piling shaping for Open-pit Coal yard. According to the requirements of standard management, each stack is compacted by a coal pusher with a height of 2 meters, the coal stack is rationally planned, and the height of the coal stack is minimized. The safety line of flood prevention and the distance of machinery peer are reserved from the angle of coal pile size to prevent the occurrence of coal yard collapse. During the period of heavy rainfall, the leaders of relevant departments are all on duty, organizing personnel to clean up and dredge water and coal at any time, to prevent large-scale collapse of coal yard and poor flow of rainwater, and to clean up coal accumulating on both sides of bucket wheel track in time, so as to ensure smooth coal-fired transshipment. When serious landslides occur in the coal yard, emergency rescue teams will be established to clean up the coal deposits outside the coal storage yard in time to minimize the coal loss caused by rainwater scouring.
