At present, it mainly relies on the water tank (sedimentation tank) in the mining area to settle the water gushing coal slime. However, the water tank in the mining area has a small capacity, and if it is not excavated in time, it will deposit, causing a large amount of water containing large particles of slime to flow into the central water tank, resulting in the coal in the central water tank. Mud accumulated rapidly, increasing the workload of clearing and excavating the central water tank
At the same time, the number of water tanks built in the mining area is large, the construction period is long, and cleaning is difficult, which affects the safety of flood control
The coal slime sedimentation effect of the water tank in the mining area is uncertain, which makes it difficult to control the water storage requirements of the central water tank

Embodiment Construction
[0011] The steps of the direct treatment method for gushing water in the coal mining face of the present invention are as follows:
[0012] Step 1: Send the water gushing from the working face directly into the primary buffer tank 1 for primary screening, discharge large pieces of dry material, and store the slime-water mixture under the sieve in the primary buffer tank to adjust the water gushing from the working face and the inconsistent processing speed of the system. fluctuations, waiting to be pumped;
[0013] Step 2: Start the mud delivery pump 2 to send the coal slime water mixture in the primary buffer tank into the horizontal screw sedimentation filter centrifuge 3;
[0014] Step 3: The coal slime water mixture is settled and separated again under the action of centrifugal force, part of the thicker coal slime is discharged from the dry coal slime outlet 3-5 and transported away by the mine truck, and part of the relatively clean water is discharged from the drain por...

The invention provides a method and equipment for directly treating water burst on a coal mining work face. The method and equipment is suitable for carrying out a direct purifying treatment on water burst on a coal mining working face in a coal mine. The water is subjected to the following steps: primary screening, buffering, carrying out centrifugal precipitation, press-filtering to remove water, loading dry coal slurry to a cart, and introducing clean water to the central water chamber. A primary buffer tank, a slurry conveying pump, a horizontal spiral settlement filtering centrifuge, a middle buffer tank, a press-filtering feed pump, and a coal slurry dehydrating filter press are connected through pipelines to form a machine set, which can directly treat the water burst on a working face. The provided method and equipment are continuous and high efficient, the coal slurry sediments in the central water chamber is greatly reduced, the normal water storing function of the water chamber is guaranteed, the frequency of cleaning on the central water chamber is reduced, and moreover the cleaning difficulty in the central water chamber is reduced too.
Description
technical field [0001] The invention relates to a method and equipment for directly treating water gushing in a coal mining face, which is suitable for direct purification treatment of gushing water in a coal mining working face, and belongs to the technical field of water gushing control in coal mines. Background technique [0002] Crack water seepage in coal mining face, water content between coal seams, dust fall in working face, cooling water of coal mining equipment, etc. are collected in large quantities during the coal mining process, engulfing coal particles and sediment in the working face, forming water gushing in the working face. At present, it mainly relies on the water tank (sedimentation tank) in the mining area to settle the water gushing coal slime. However, the water tank in the mining area has a small capacity, and if it is not excavated in time, it will deposit, causing a large amount of water containing large particles of slime to flow into the central wa...
