Embodiment Construction
[0056] 1. Introduction to Xingshan Iron Mine of Shougang Mining Company
[0057] Xingshan Iron Mine is the first underground mining mine built by Shougang. The mining range of the first phase of Xingshan underground mining is determined to be above the level of -330m. The mine scale of the first phase project is 3.2 million t / a of ore and 250,000 t / a of rock (among them, 150,000 t / a of quasi-excavated rock and 100,000 t / a of developed rock.).
[0058] According to the distribution of ore bodies, 13 ore rock slide shafts are built in the mining area. The ore rock in the mining area above -180m reaches the -180m level through the slide shafts. The transportation level at the -180m stage adopts a circular layout. In this way, the ore rocks from 13 ore chute shafts are transported to the main chute shaft to prepare raw materials for the lower crushing and lifting system.
[0059] The ore transportation in the stope is driven by a 20t electric locomotive and the 10m3 bottom side u...

The invention provides a ground remote control system for downhole electric locomotives, and belongs to the technical field of downhole mining. The ground remote control system for the downhole electric locomotives comprises a dispatching and ore blending unit, a locomotive unit, an operation unit, an ore loading unit and an ore unloading unit. The dispatching and ore blending unit comprises a digital ore blending system and a digital locomotive dispatching system; the locomotive unit comprises a downhole electric locomotive transport system and an electric locomotive automatic protection system; the operation unit comprises a downhole narrow gauge signal concentrating locking control system, a control console system, a wireless communication system a 100 M network communication system and an uninterrupted power system; the ore loading system comprises a draw shaft remote ore loading system and a draw shaft remote ore loading video monitoring system; the ore unloading system comprises an automatic ore unloading system and an unloaded-ore automatic sweeping system. The ground remote control system for the downhole electric locomotives has the advantages that work of a downhole electric locomotive driver and work of an ore drawing worker are integrated, the working position is moved to the ground from the downhole, the intrinsic safety level is improved, occupational diseases are avoided, safe and efficient operation of the electric locomotives is ensured, operation is simplified, the operation ratio of the electric locomotives is improved, machine-hour efficiency of the electric locomotives is improved, production and organization efficiency is improved, and stability of the output grade is improved.
Description
technical field [0001] The invention belongs to the technical field of underground mining control, and in particular provides a ground remote control system for underground electric locomotives. The ground remote control system for electric locomotives has realized a new production operation mode of unmanned underground electric locomotive transportation and ground remote control. Background technique [0002] The underground mine electric locomotive transportation system is the main artery of mine transportation, and the safe and efficient operation of electric locomotives is a key link in underground mining production. With the continuous expansion of the scale of underground mining, the transportation tasks of underground electric locomotives closely related to production are becoming more and more heavy. Usually, measures such as increasing the number of transportation vehicles and trains, or increasing the speed of vehicles are adopted to adapt. The transportation equi...
