Abstract

The invention provides a mechanical mining method of a thick and large ore body heading machine, and relates to the technical field of non-coal mining. The mechanical mining method of the thick and large ore body heading machine comprises the following steps: A, an ore body is divided into a plurality of layers in stages or subsections in the vertical direction, and the height of each layer is a single stoping height; each layered ore body is divided into ore block units on a plane; B, an ore removal roadway is arranged in each ore block unit, and a stoping access is arranged along the ore removal roadway; C, the stoping accesses in the adjacent layered ore block units are crossed in an X shape; D, mechanical ore breaking stoping is conducted in the stoping accesses through a heading machine; E, during stoping of the heading machine, ventilation and dust removal are achieved in a press-in type and draw-out type combined ventilation mode; and F, filling is conducted timely after the stoping of each stoping access is finished. In a vertical space, the stoping accesses in the ore block units can form a three-dimensional net-shaped structure, a space structure beneficial to the stability of a filling body is formed, and the probability of ore body collapse in the mining process is reduced.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a mechanical mining method of a roadheader for thick and large ore bodies. Background technique [0002] Coal has been continuously mined through mechanical rock breaking. People began to think and proposed to replace the non-coal mining technology based on blasting with continuous cutting equipment. [0003] In the mining of thick and large ore bodies inclined to steeply inclined, when the ore body is weak, broken and unstable, drilling and blasting mining has poor safety operating conditions, high difficulty in supporting operations, low degree of mechanization, limited production capacity, and poor operating conditions. high cost issues. With the changes in the industry and social environment, non-coal mines have a strong internal demand for mechanized operations. Mechanical rock breaking is an important development trend in future mining operations and will play an important ...
