Hoisting device for deep well underground mining

Abstract

The invention discloses a hoisting device for deep well underground mining. The hoisting device comprises a supporting frame shell, a servo motor is fixedly installed in the supporting frame shell, alead screw is fixedly installed at the bottom of the servo motor, and the lead screw is fixedly installed in the supporting frame shell. The hoisting device not only realizes a hoisting function for deep well underground construction, but also can be used for deep well underground ore bed monitoring and earth surface monitoring through the position of a pressure sensor installed in the device. Whether sedimentation occurs or not can be monitored through signal changes of the pressure sensor, the sedimentation depth and scale can be estimated, the measurement precision is high, and the safety of underground workers is improved. According to the hoisting device, a supporting frame increases the contact points with the ground, the using stability is enhanced, the toppling phenomenon is avoided, using is convenient, toppling can be effectively prevented, the device is protected against damage, and meanwhile the safety of the underground workers is protected.

Description

technical field [0001] The invention belongs to the field of mine mining, in particular to a hoisting device for deep underground mining. Background technique [0002] Mine underground mining is to excavate a series of shafts from the ground to the ground. The whole production process is carried out underground, and all kinds of operating equipment need to be transported to the underground roadway for installation and use. In coal mine production, the underground mining method is the most important method. Therefore, it is of great practical significance to study underground mining technology. The application of underground mining technology must be adapted to the coal mine geology and coal seam distribution, and the mining plan must be formulated in advance to determine the application of equipment and support methods. In open-pit mining, Generally, the direct mining method is adopted, but due to the constraints of the environment and equipment in underground mining, the mi...

Problems solved by technology

[0003] However, due to the constraints of the environment and equipment in underground mining, the mining method from top to bottom is usually adopted. Directional mining is no longer limited to the mining of a certain link, but proceeds from the whole, using directional drilling means to Coal mining is carried out in the corrected position. The existing hoisting device for deep underground mining has a single function and cannot monitor the underground ground subsidence. The underground subsidence is the loss of ground elevation caused by the combined effects of natural factors and human factors. At the same time, the existing Most of the supporting feet of the underground mining hoisting device are fixed in length. When the underground mine layer is uneven, it is easy to cause the underground mining hoisting device to shake and cause damage.
