Non-destructive mining method

Abstract

The invention discloses a non-destructive mining method, which comprises the following steps on a whole: firstly, distributing a mining area tunnel including a coal mine transportation corridor and a material and equipment transportation corridor; installing a hydraulic support on a working plane, a scraper plate conveyor and a coal mining machine on the front side of the support, and a filling body transportation machine on the rear side of the support; and starting equipment, and supporting the coal mining space of a coal mining machine by the front part of the support and the filling operation space by the rear part of the support while the coal mining machine is propelled forward. A top plate is prevented from collapsing through the temporary supporting and timely filling modes of the support, so that a series of accidents or disasters caused due to collapse of the top plate can be avoided, the influence of coal recovering on the ambient environment of a mining field can be improved to the maximum extent, not only can the coal resource recovery rate be increased, but also the green and environment-friendly mining of the coal resources can be realized; the non-destructive mining method also has good multi-geological condition adaptability, and can increase the resource recovery rate while the mining safety is enhanced.

Description

Technical field [0001] The invention relates to a mining method, in particular to a lossless mining method, and belongs to the field of mining mining. Background technique [0002] With the gradual development of mining in my country, the phenomenon of subsidence and subsidence of underground and surface mined-out areas has had a serious impact on people's normal life. Traditional mining methods (such as strip mining), on the one hand, to prevent the occurrence of collapse, the coal cannot be fully mined, resulting in a large loss of unmined resources, on the other hand, it is also unable to sink the ground due to underground mining. Therefore, the damage to the surface environment is becoming more and more serious. In addition, with the increase of mining depth, accidents and disasters caused by roof collapse are increasing, which seriously endangers the safety of mining workers and restricts the development of the mining industry. [0003] In order to avoid various adverse effe...

AI Technical Summary

Problems solved by technology

Traditional mining methods (such as strip mining), on the one hand, cannot fully extract coal mines to prevent subsidence, resulting in a large loss of unexploited resources; Therefore, the damage to the surface environment is also becoming more and more serious

In addition, with the increase of mining depth, accidents and disasters caused by roof collapse are increasing, which seriously endanger the safety of mining workers and restrict the development of mining industry

[0003] In order to avoid various adverse effects caused by underground mining, people have developed preventive measures to fill a large number of filling bodies into the goaf, but the existing filling methods cannot be carried out simultaneously with mining, and need to be completed after the ore body is mined. Filling after a period of time not only seriously wastes manpower and material resources, but also has low work efficiency, and cannot guarantee the personal safety of workers when filling is not completed, and there are still certain potential safety hazards
