Abstract

The invention provides a mining coal transportation system. The mining coal transportation system comprises a coal loading and unloading device, a coal conveyor belt, a variable frequency motor, a coal quantity monitoring device and a controller, wherein the coal loading and unloading device is used for loading coal collected by a coal mining machine onto the coal conveyor belt; the coal conveyorbelt is used for transporting the coal in a conveying manner; the variable frequency motor is used for providing conveying power for the coal conveyor belt; the coal quantity monitoring device is usedfor monitoring the coal quantity on the coal conveyor belt; the controller is in communication connection with the coal loading and unloading device, the coal quantity monitoring device and the variable frequency motor; and the controller is used for monitoring the coal quantity on the coal conveyor belt through the coal quantity monitoring device and controlling the operation speed of the variable frequency motor according to the coal quantity on the coal conveyor belt. According to the technical scheme provided by the invention, the coal quantity monitoring device is arranged and is used for monitoring the coal quantity on the coal conveyor belt, so that the operation speed of the system is adjusted in real time according to the coal quantity on the coal conveyor belt; the power energyconsumed by the transportation system is reduced while the coal transportation efficiency is ensured.

Description

technical field [0001] The invention relates to the technical field of coal mining, storage and transportation, in particular to a mining coal transportation system. Background technique [0002] In the process of underground coal mining in coal mines, due to the differences in the distribution of coal and the coal digging energy per unit time of the shearer, the coal production per unit time of the coal mine varies greatly. The mining coal transportation system is used for the immediate transportation of the coal mined by the coal mining machine in the coal mine. [0003] The prior art mine coal transportation system usually operates at a constant speed. In order to ensure smooth coal transportation, the operation speed of the transportation system is usually adjusted to a speed value that can carry the maximum coal production. However, in the period of time when coal production is small, the existing mining coal transportation system still maintains high-speed operation, ...
