Problems solved by technology

Especially for the mining of unstable thick and large ore bodies, due to the weak and broken ore bodies, the allowable exposure time is short and the exposure area is small, and it is more faced with low mechanization and intelligence, low mining efficiency, limited production capacity, high production costs, and poor safety. And other issues

Embodiment Construction

[0019] The technical solutions of the present invention will be clearly and completely described below in conjunction with embodiments.

[0020] Such as Figure 1-Figure 3 As shown, the non-explosive mining method for thick and large ore bodies based on the intelligent roadheader provided by the embodiment of the present invention is suitable for the mining of weak, broken, unstable, and high-value hard rock ore bodies with a thickness of 20 m and above, and is a mechanical mining method. Provided new ideas.

[0021] The embodiment of the present invention provides a non-explosive mining method for thick and large ore bodies based on intelligent roadheaders. The method includes: dividing the thick and large ore bodies into multiple panels along the strike, and the panels are vertically divided into multiple segments. There are multiple layers in the segment, and each layer is divided into a number of vertical mining approaches 11 .

[0022] Each panel is 42-112m long, the wi...

Abstract

The invention discloses a thick and large ore body non-explosive mining method based on an intelligent heading machine. The method comprises the following steps that A, an ore body is divided into a plurality of panels along the trend, each panel is provided with a plurality of subsections in the vertical direction, each subsection is internally provided with a plurality of sub-layers, and each sub-layer is divided into a plurality of stoping drifts perpendicular to the trend of the ore body; and every two adjacent upper and lower layers form one group, and each group is subjected to stoping and filling from top to bottom; and B, the cross sections of two adjacent stoping drifts on the same layer are arranged in a staggered mode, every two adjacent upper and lower layers are arranged in a mode that a positive quasi-trapezoid corresponds to an inverted quasi-trapezoid, a goaf of one stoping drift on the upper layer and a goaf of one corresponding stoping drift on the lower layer are jointly served as a filling unit for filling, the upper layer is returned for stoping, the position of the lower layer corresponding to the goaf on the upper layer is subjected to stoping, after the filling unit is formed, filling is conducted immediately till the filling of the group is completed, and then the next group is subjected to stoping. According to the method, mechanical intelligent, safe, efficient and low-cost non-explosive continuous mining can be carried out on the soft-broken thick and large ore body by using equipment such as the intelligent heading machine.

Description

technical field [0001] The invention relates to the technical field of non-coal mining, in particular to a non-explosive mining method for thick ore bodies based on an intelligent roadheader. Background technique [0002] Metal mines still generally adopt the traditional drilling and blasting method, which has problems such as poor safety conditions and scattered and discontinuous operation links, which is not conducive to the realization of automation and intelligence. Especially for the mining of unstable thick and large ore bodies, due to the weak and broken ore bodies, the allowable exposure time is short and the exposure area is small, and it is more faced with low mechanization and intelligence, low mining efficiency, limited production capacity, high production costs, and poor safety. And other issues. [0003] In order to adapt to the requirements of the state and governments at all levels on safety production and other related policies under the new situation, and ...
