Abstract

The invention discloses a downhole water-coal separation system. The downhole water-coal separation system comprises a downhole coal raker, a receiving hopper, a shredder, a spiral sludge dewatering equipment and a belt conveyor. The invention further discloses a corresponding water-coal separation method. The method comprises the steps of mounting, primary water-coal separating, secondary water-coal separating, crushing, concentrating and dehydrating, wherein concentrated and dewatered coal cakes are conveyed to a skip bucket by mine cars. According to the system and the method, the mountingis convenient, the operating is simple and convenient, the field adaptability is high, the water-coal separating effect is good, seaborne coal, silt coal and even bulk coal can be raked out conveniently, the influence on mine drainage caused by blockage to a main water pump is prevented, tasks which are difficultly completed by downhole equipment in the past can be completed, and blockage does notoccur. According to the system and the method, the cycle of excavation of a borehole bottom sump of a coal mine can be prolonged, so that the labor intensity of workers is lowered, the blockage to the main water pump is reduced, and the downhole working environment of the coal mine is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery, in particular to the water-coal separation technology. Background technique [0002] During the flow of underground water in coal mines, a large amount of coal will be trapped, forming water coal with a coal content of 10%-20%. If these water coals are not treated, they will be directly discharged into the water tank at the bottom of the well, and after a long period of deposition in the water tank , the section of the water tank will be reduced, and the water storage capacity of the water tank will be reduced. At the same time, the water flow will also entrain a large amount of silt into the suction port of the main water pump, affecting mine drainage. Therefore, before the water-coal mixture flows into the bottom tank, it is necessary to separate the water-coal. In the case where water-coal separation is required underground, sometimes the coal content in water-coal will be very h...
