📝 Foreword / 前言 ai_extracted
This standard is a revision of MT 213-1991 "General Technical Specifications for Raise Boring Machines Used in Coal Mines". This standard supersedes MT 213-1991. The main changes in this standard compared with MT 213-1991 are as follows: ——Added terms, definitions, and corresponding English terms such as "thrust cylinder", and removed terms already defined in other standards, such as "stabilizing drill pipe" (1991 edition, Clause 3.6; this edition, Clause 3.6); ——Modified the model designation method, added identification for "electric drive" and "electric control" types of raise boring machines, added torque as a main parameter, and correspondingly revised the marking examples (1991 edition, Clause 4.1; this edition, Clause 4.1); ——Modified the basic parameter items and parameter series, divided into three parts: "main unit", "pump station", and "control console", to add and improve the basic parameter items for raise boring machines, and added the main parameter series (1991 edition, Clause 4.2 and Table 1; this edition, Clause 4.2 and Table 1); ——Added the model designation for raise boring machines (see Clause 4.3); ——Restructured and updated the basic technical requirements, separately listed safety requirements, and added safety and technical requirements for dedicated flatbed vehicles, aluminum alloy materials, polymers, high-pressure hoses, cables, and wheel-rail type chassis (1991 edition, Clause 5.1; this edition, Clauses 5.1 and 5.2); ——Modified "sealing performance requirements" to "pressure resistance and sealing performance", and refined the original requirements (1991 edition, Clause 5.3; this edition, Clause 5.4); ——Deleted clauses related to "industrial testing" (1991 edition, Clauses 5.7, 6.7, and Table 2, Item 7); ——Deleted clauses related to "complete supply scope of raise boring machines" (1991 edition, Clause 5.8); ——Modified the content of inspection rules to match the clauses in this edition (1991 edition, Table 2; this edition, Table 3); ——Modified and refined the marking requirements, and specified specific provisions for nameplates, marking plates, and indicator plates of raise boring machines (1991 edition, Clause 8.1; this edition, Clause 8.1); ——Added the item "instruction manual", standardized the requirements for manual preparation, and proposed several key warning contents (see Clause 8.2); ——Deleted the requirements for marking plates and instrument surfaces in the "packaging" item (1991 edition, Clause 8.2.4), and modified the packaging requirements for exposed piston rods, threads, etc. (1991 edition, Clause 8.2; this edition, Clause 8.3); ——Added the technical documents included in the packaging box, "Documents and materials provided for raise boring machines under the management of mining safety marking products" (see Clause 8.3.6 e)), and deleted "other documents specified in the contract" (1991 edition, Clause 8.2.7 h); ——Deleted the commercial requirements in the storage item (1991 edition, Clause 8.4.3).
