Abstract

The invention provides a shortwall hydraulic mining method along strike and belongs to the technical field of coal mining. The mining method is used for solving the problems of difficult face ventilation, serious gas harm, imperfect ventilation system, poor operation safety, unavailability for coal seams with high gas and serious spontaneous combustion tendency, relatively narrow application range, low recovery ratio and the like of the traditional hydraulic mining methods. According to the shortwall hydraulic mining method along strike, stope ventilation is focused and the arrangement of a hydraulic mining tunnel and the support pattern of the working face are improved, and therefore, a mining method conforming to ventilation and gas control requirements is established. The shortwall hydraulic mining method along strike is reasonable in process design, safe and reliable, and capable of well meeting the requirements of the underground hydraulic mining operations; as a result, the effective support for an exposed roof on the hydraulic mining face and the reasonable ventilation of the working face are realized, and the coal mining efficiency and the operational safety are remarkably improved.

Description

technical field

[0001] The invention belongs to the technical field of coal mining, and relates to an underground coal mining method in a coal mine, in particular to a trending short-wall hydraulic coal mining method for an inclined difficult-to-mining coal seam, which provides an effective guarantee for ventilation safety of a hydraulic coal mining face. Background technique

[0002] Existing coal mining methods include mechanical coal mining, hydraulic coal mining, and blasting coal mining. When the mechanical coal mining method cannot be used under some conditions with large dip angles or unstable coal seams, the blasting coal mining method and hydraulic coal mining method are often used. The hydraulic coal mining method is a mechanized coal mining technology that uses high-pressure water jets to break the coal body, and completes its transportation, lifting and other processes with the help of hydraulic power.

[0003] The characteristics of hydraulic coal mining: coal ...
