Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0012] A kind of thin coal seam efficient fully mechanized mining technology, as shown in Figure 1, comprises the following steps:

[0013] Firstly, there are two working face material lanes 1 and one working face common transport lane 5 arranged side by side. The adjacent lanes are the working face, and the middle working face common transport lane 5 is selected as the common lane. Each working face has a working face Coal shearer 4, working face scraper conveyor 2, hydraulic support 3, and then the two working faces are side by side for comprehensive mechanized coal mining.

[0014] The present invention applies the coal mining technology of the opposite-drawing working face combined with the comprehensive mechanized coal mining technology to the working face of thin coal seam mining. First, arrange three roadways side by side, and arrange two wor...

Abstract

A high efficiency fully-mechanized mining process of low coal seam is developed by combining double-unit face mining technology on the basis of comprehensive mechanized coal mining technology of low coal seam, which comprises following steps that two face material roadways and a face sharing conveyance road are parallel arranged, the space between the adjacent roads is used as working faces, the face sharing conveyance in the middle is chosen to be used as a sharing road, and a face coal-winning machine, a face scraper conveyer, and a hydraulic support are evenly arranged on each working face, and the two working faces simultaneously proceed comprehensive mechanized coal mining in parallel. Compared with the comprehensive mechanized coal mining technology, the invention lacks a road, which reduces myriatonne drivage ratio of mines, and saves costs, and the two working faces are simultaneously arranged to produce, which is beneficial for management, can effectively use labor resources, material resources, reduces storage rate of equipment part, and lowers cost input, such as reducing a bridge transfer machine.

Description

technical field [0001] The invention relates to a thin coal seam recovery technology, in particular to a thin coal seam comprehensive mechanized coal mining technology for pulling working faces. Background technique [0002] In the current existing technology, blast mining or high-grade general mining technology is mainly used for mining inclined and gently inclined thin coal seams, and there are currently relatively advanced thin coal seam comprehensive mechanized coal mining techniques, and the characteristics of thin coal seam comprehensive mechanized coal mining techniques ( 1) For single-face production, one transportation lane and one material lane are arranged, totaling two lanes. (2) Supporting machinery and equipment: a shearer, a hydraulic support, a scraper conveyor on the working face, and a bridge transfer machine. (3) The coal mining method is positive knife or "∞" type coal mining method. (4) Technological process: cutting coal → moving frame → sliding forwa...
