Continuous coal mining machine end slope mining ventilation and dust removal system and method

Abstract

The invention belongs to the technical field of ventilation and dust removal for end slope mining of an open pit mine, and particularly relates to a continuous coal mining machine end slope mining ventilation and dust removal system and method. The system and method aim to solve the problems that dust of a continuous coal mining machine end slope mining working face is difficult to control, accordingly normal work of electric control systems such as video monitors and the adaptability of a dust removal device to the length change of a mining cave are influenced, and air of a stope is polluted.The system comprises a local ventilator, an air supply duct, a combined ventilation dust control device, a dust remover and a dust removal air duct which are sequentially distributed on the working face from outside to inside. One end of the air supply duct is connected with the combined ventilation dust control device, the other end of the air supply duct is connected with the press-in type local ventilator, and the air supply duct is distributed on a belt conveying system through a suspension device. One end of the dust removal air duct is connected with the combined ventilation dust control device, the other end of the dust removal air duct is connected with the dust remover, the dust removal air duct and the dust remover are both distributed on the belt conveying system, and the press-in type local ventilator is arranged outside the mining cave.

Description

technical field [0001] The invention belongs to the technical field of ventilation and dust removal for end-side mining in open-pit mines, in particular to a ventilation and dust removal system and method for end-side mining of continuous coal mining machines. Background technique [0002] The production of open-pit coal mines plays an important role in my country's and even the global coal industry. According to relevant data, there are currently more than 400 open-pit mines in my country, and the annual open-pit coal mining volume exceeds 500 million tons, accounting for nearly 15% of the country's total coal production. Due to the characteristics of the mining process of open-pit mining, with the rapid increase in the output of open-pit coal mines, my country's annual open-pit coal pressure is nearly 30 million tons, especially in major coal producing areas such as Inner Mongolia, Ningxia, Shanxi, Shanxi and Xinjiang. Due to unplanned mining in the early stage, the coal se...
