摘要
煤炭是我國的基礎(chǔ)能源和重要原料，在國民經(jīng)濟中占有重要的戰(zhàn)略地位，這是中國當前的國情。目前，煤炭行業(yè)面臨著一些情況：安全基礎(chǔ)薄弱，安全生產(chǎn)形勢嚴峻；資源綜合利用程度不夠，礦區(qū)生態(tài)環(huán)境亟須改善；先進與落后生產(chǎn)能力并存，整體技術(shù)水平低。
本課題針對的主要方向為礦井機電設(shè)備。要實現(xiàn)高產(chǎn)高效的采煤，必須進行正確的機電設(shè)備選型。
根據(jù)課題的設(shè)計要求，本設(shè)計主要從礦井地理位置，井田走向，頂?shù)装鍡l件，水文地質(zhì)，礦井開拓系統(tǒng)，通風(fēng)及排水要求，主運輸系統(tǒng)等礦井基本情況出發(fā)，進行采煤機選型設(shè)計，液壓支架選型設(shè)計，刮板輸送機選型設(shè)計，皮帶輸送機選型設(shè)計，提升設(shè)備選型，排水設(shè)備選型設(shè)計，通風(fēng)設(shè)備選型設(shè)計。并繪制三機配套圖、水泵房布置圖、通風(fēng)機三視圖、提升電控系統(tǒng)原理圖。
關(guān)鍵詞：采煤機；液壓支架；刮板輸送機；皮帶運輸機；提升機；排水與通風(fēng)；選型設(shè)計
ABSTRACT
Coal is China's basic energy and important raw materials, the national economy in an important strategic position, it is China's national conditions.At present, the coal industry faces some situation: safe foundation is weak, the safety production grim situation, Comprehensive utilization of resources enough to improve ecological environment of mining, urgent. Advanced and backward production capacity, technical level is low.
This topic in the main direction for mine electrical equipment.To achieve high efficiency of coal mining, must be the correct selection of equipment.
According to the subject, this design main design requirements from the mine geographical location, the field direction, roof and floor condition, hydrology geology, mine exploit system, ventilation and drainage requirements, main transport system based on the basic case, the mine coal Jinan type design, selection of hydraulic support design, scraper conveyor belt conveyor design, selection of design, selection of equipment type selection, ventilation and drainage design selection of equipment design.And map form a complete set of compressors, arrangement plan of the water pump, fan Sultanship, electric control principle diagram of the system.
Key words: shearer, hydraulic support ,conveyor, belt conveyor,hoist,
drainage and ventilation, Selection design
