Embodiment Construction
[0024] The supporting method for fully mechanized mining equipment of the present invention comprises the following steps:
[0025] In step 101, a shearer with a predetermined height and power is selected according to the mining height, hardness, and daily output of the working face, and according to the working clearance of the shearer. Preferably, the shearer can also be selected according to the service life. In a preferred embodiment, when the planned accumulated coal excess is less than or equal to the lifetime coal excess x 120%, the shearer is selected. In addition, it is also preferable to select the shearer according to the overhaul time. For example, when the planned overhaul coal volume is less than or equal to overhaul coal volume x 120%, the shearer is selected.
[0026] Shearers can be selected according to the rules in Table 1 below, along with face characteristics:

The invention discloses a matching method of mechanized mining equipment, comprising the following steps of: selecting a coal mining machine with preset height and power according to the mining height, the hardness and the daily output of a working face and a working clearance of the coal mining machine; selecting preset quantity of hydraulic supports according to the length and the pressure of the working face and working clearances among the hydraulic supports; selecting a scraper conveyer with preset power according to the coal transferring amount, the length of the working face, the transportation distance and the arrangement mode of the working face; and respectively calculating comprehensive clearances among the coal mining machine, the hydraulic supports and the scraper conveyer, sequencing the coal mining machine, the hydraulic supports and the scraper conveyer according to the comprehensive clearances, and selecting equipment with minimum comprehensive clearance as matching equipment. By adopting the mechanized matching method, the utilization ratio of the mechanized mining equipment is greatly improved, and the generated matching scheme can be ensured to be feasible and better.
Description
technical field [0001] The invention relates to the field of mining, in particular to fully mechanized coal mining equipment and matching and scheduling methods thereof. Background technique [0002] The main equipment of fully mechanized mining face includes shearer, hydraulic support, scraper conveyor, loader, crusher and other equipment. Among them, the structural dimensions of the shearer, hydraulic support, and scraper conveyor require a certain coordination relationship. [0003] After the coal shearer, hydraulic support and scraper conveyor in a set of equipment are put into use, due to a period of use, they usually need to be overhauled and replaced. The overhaul period of the equipment is different, and the equipment cannot be used in groups forever. The shearer of the first unit may be matched with the second or other hydraulic supports and scraper conveyors. [0004] The traditional matching method of fully mechanized mining equipment is carried out by supportin...
