Abstract

The invention discloses a fast installation method of ten-million-ton scale fully mechanized caving face equipment and belongs to sinking and driving engineering of mines. The method is innovatively characterized in that open-off cuts on a working surface are widen to improve the transportation mode and installation method of a hydraulic support and the supporting mode of the open-off cuts. By virtue of the improvements, the installation time of the ten-million-ton scale fully mechanized caving face equipment is realized, the construction period is shortened and the installation progress of the working surface is accelerated.

Description

technical field

[0001] The invention relates to mine shaft and roadway engineering, and is mainly used in fully mechanized caving working face cutting hole brush expansion and equipment installation engineering. Background technique

[0002] At present, when the equipment is installed in the 10-million-ton fully-mechanized mining and fully-mechanized caving face of the coal mine, the first step is to cut the eye in the construction face. Due to the huge equipment, the span of the eye is generally 8-10m. The beams are used to strengthen the support, and then the equipment installation work on the working face is carried out. When the equipment is installed, remove the single pillar and replace it with a fully mechanized mining support.

[0003] This brings up the following three issues:

[0004] (1) The span of the working face cutout is large after the construction is completed, and the workload is heavy when using single pillars to strengthen the support. More than 1,000 ...
