For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 15663.3-2008 Terms relating to coal mining - Part 3: Underground mining GB 25974.1-2010 Powered support for coal mine - Part 1: General specification GB 50536 Code for design of coal mine full-mechanized mining district GB 50581 Standard for allocated mine monitoring and controlling system of coal industry MT/T 84 Shearer - Types and basic parameters MT/T 105 General technical specification of chain conveyors 3 Terms and definitions For the purpose of this document, terms and definitions given in GB/T 15663.3- 2008 and the following apply. For ease of use, some of the terms and definitions in GB/T 15663.3-2008 are repeatedly listed below. 3.1 working face. 3.8 left working face Standing on the head of the scraper conveyor, facing the tail of the scraper conveyor, the working face where the coal wall is located on the left-hand side. 3.9 right working face Standing on the head of the scraper conveyor, facing the tail of the scraper conveyor, the working face where the coal wall is located on the right-hand side. 3.10 system integration matching According to the coal seam occurrence conditions and mine design requirements, carry out the coordination design of the matching relationship of fully-mechanized mining face’s fully-mechanized mining equipment, liquid supply system, automatic control system, dust reduction system, power supply system, etc. 4 Technical requirements 4.1 General requirements 4.1.1 Fully-mechanized mining face’s system integration matching mainly consists of the selection of system related equipment such as coal mining, transportation, support, liquid supply, power supply and dust prevention of the working face AND the coordination design of matching relationship. At the same time, it shall meet the requirements of systems such as drainage, ventilation, fire prevention, monitoring of the working face. Fully-mechanized mining face mainly refers to the working face of fully-mechanized mining of thin seam, fully- mechanized mining in medium-thickness coal seam, fully-mechanized mining with large cutting height, fully-mechanized mining with super large mining height, fully-mechanized top coal caving, fully-mechanized mining with large cutting height and top coal caving, fully-mechanized mining with super large cutting height and top coal caving, fully-mechanized mining with large dip angle and fully-mechanized top coal caving with large dip angle. 4.1.2 The basic contents of fully-mechanized mining face’s system integration matching are shown in Figure 1. - Belt conveyor; - Liquid supply equipment; - Power supply equipment; - Dust prevention equipment; - Ventilation equipment; - Drainage equipment; - Monitoring equipment; - Other auxiliary equipment; - Equipment capacity accounting; - Integration matching verification. Figure 1 -- Basic contents of fully- mechanized mining face’s system integration matching 4.1.3 The results of fully-mechanized mining face’s system integration matching mainly consist of the equipment selection basis, process, results of fully- mechanized mining equipment, liquid supply system, power supply system, dust prevention system, etc. of the working face and matching relationship design drawings. 4.2 Basic requirements 4.2.1 The design of fully-mechanized mining face’s system integration matching shall be based on coal seam occurrence conditions, mining method selection, working face length, machine mining height, roadway section size, mine construction target, etc., and shall meet the relevant provisions of GB 50536. 4.2.2 The design of fully-mechanized mining face’s system integration matching shall be based on the basic principles of intrinsic safety, technical feasibility, economic rationality, equipment reliability and equipment technology forward- looking. 4.2.3 The design of fully-mechanized mining face’s system integration matching shall be matched with the design of overall system of the mine. 4.2.4 Fully-mechanized mining face shall be subjected to the system integration matching design before putting into production. 4.3 Equipment selection and system integration matching requirements 4.3.1 The technical parameters of fully-mechanized equipment and the matching auxiliary equipment such as liquid supply, power supply, drainage, ventilation, dust prevention, fire prevention and monitoring shall be adapted to the working face’s coal seam occurrence conditions, shall meet the requirements of the working face’s mining height, length, inclination, mine 4.3.5 The working face equipment of fully-mechanized mining with large dip angle and fully-mechanized top coal caving with large dip angle shall be adapted to the requirements of large dip angle working face on equipment installation power, stability and safety protection. It shall have reliable anti-fall, anti-skid and anti-flying devices and measures. 4.3.6 It shall select open equipment such as communication interfaces and protocols, ensuring communication and coordinated control between equipment. 4.3.7 The design of working face’s system integration matching requires specialized design, and the design documents shall be signed and confirmed. 5 Matching verification 5.1 The equipment of first matching shall be subjected to the joint test operation of complete set of equipment on the ground before going down the mine, to ensure the smooth installation and application of the working face. 5.2 The laying length of the equipment to be subjected to the ground joint test operation shall be not less than 30 m. The laying equipment shall include hydraulic support, shearer, scraper conveyor and other main matching equipment (such as central, transition, face end, advance hydraulic supports, part of the line pans and all the routing pans at the drive head unit and drive end unit of scraper conveyor, etc.), to verify whether the complete set of equipment meets the overall layout requirements of the working face equipment. 5.3 Verify all the functions that the stand-alone equipment shall have, and check the equipment for problems during the assembly process and during the no- load operation. Stand-alone equipment can be subjected to the joint test operation of complete set of equipment after passing the independent operation. 5.4 For the joint test operation of complete set of equipment, first check whether each equipment is produced according to the matching drawings, and then check whether the equipment matching relationship is correct, whether the connection mode is reasonable, whether the maintenance space is suitable, whether the operation mode is reasonable, whether the automatic control mode is safe and reliable, whether the working face’s signal transmission, reception and display are normal, and whether the complete set of equipment is in normal operation state. 5.5 After the equipment joint test operation is qualified, the coal production enterprise shall issue a verification report on the ground joint test operation of the work face equipment, which shall be signed and confirmed by the relevant ......
