Description

Mining dual-power dual-water-level automatic device
Technical Field
The utility model relates to a colliery is electrical equipment control in pit and the technical field who uses, concretely relates to mining dual supply two water level automatics.
Background
In the process of mine construction and production, ground water and underground water flow into the mine through various channels, and when the water flowing into the mine exceeds the normal drainage capacity, the mine is in flood. Mine flood (commonly referred to as flooding) is one of the main common disasters in coal mines. Once the water permeation occurs, the normal production of the mine is influenced, casualties can be caused sometimes, the mine and a mining area are submerged, and the damage is very serious. Therefore, the mine waterproof work is well done, and the method is one of important contents for ensuring the safe production of the mine.
Mine water sources are divided into ground water and underground water.
1. Mine flood caused by ground water. When there are water accumulation in rivers, lakes, ponds, reservoirs, ditches, etc. near mines and seasonal rainwater, the water level rises suddenly and exceeds the elevation of the wellhead of the mine to flow into the underground, or seeps into the underground from cracks, faults or subsidence areas to cause flood, and the water source is surface water. The water hazard generally includes the following: 1) The mine in low-lying area breaks the dike around the mine by surface water and flows into the wellhead, or due to improper selection of the position for pushing stone hill, furnace dust and the like, the mine is flushed into nearby rivers by flood or rainwater for a long time, so that the river bed is heightened or river water exceeds the dike or flood-stopping dam and directly enters the wellhead. This surface water is violent and is accompanied by a lot of silt and gravel. If the prevention is improper, well flooding accidents are often caused; 2) The surface water is communicated with the soft gravel stratum, and when the shaft is tunneled and penetrates through the aquifer of the washup layer, the surface water is gushed into the well along the fracture of the gravel stratum to cause well flooding; 3) The surface water is communicated with the aquifer of the coal seam top and bottom plate or communicated by the fault, and the surface water enters a roadway through the aquifer or the fault, so that a flood accident occurs; 4) Once the caving zone enters an old kiln or is communicated with a surface water system after the coal seam is excavated, surface water can also flow into a mine, so that flood accidents are caused.
2. Mine flood caused by underground water. The underground water comprises underground aquifer water, karst caves, fault water, old air water and the like. The conditions of flood caused by underground water include the following generally: 1) The gravel layers, sand layers and lime rock layers with karsts in the ground contain a large amount of water, called aquifers. When the excavation work approaches or penetrates through the water accumulation area, water permeation accidents can be caused; 2) The fault and the rock stratum nearby the fault are relatively broken, water is contained in the broken zone or the broken zone is communicated with surface water and a water-containing layer, and when the broken zone is tunneled, the situation is met, and the water inrush accident is easily caused. 3) In the excavated old roadway and cavity, a large amount of water is often accumulated, which is called as old empty water. Old and vacant water is often the main cause of mine flood accidents. The old air water is characterized by large water pressure, and once the old air water is dug thoroughly, the old air water is fierce in coming, and has great destructiveness.
Although traditional type water pump has been intelligent, all is the unit control, satisfies the mine that the infiltration volume is little, or many water pump control, and occupation space is big and single power, in case power failure etc. must take place the water level and transfinite or bigger accident, cause the loss that can not retrieve.
