摘要
煤炭是我國的基礎(chǔ)能源和重要原料,在國民經(jīng)濟(jì)中占有重要的戰(zhàn)略地位,煤炭生產(chǎn)的高產(chǎn)高效得煤炭企業(yè)發(fā)展的-------
礦山機(jī)械---------在作用
本課題主要研究對象為礦井機(jī)電設(shè)備,通過對機(jī)電設(shè)備的正確選型,為實(shí)現(xiàn)采煤的高產(chǎn)高效提供技術(shù)支持。
根據(jù)課題的設(shè)計(jì)要求,本設(shè)計(jì)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,主副井系統(tǒng),主運(yùn)輸系統(tǒng)等礦井基本情況出發(fā),進(jìn)行采煤機(jī)選型計(jì)算,液壓支架選型計(jì)算,刮板輸送機(jī)選型計(jì)算,通風(fēng)設(shè)備選型計(jì)算,排水設(shè)備選型計(jì)算,皮帶輸送機(jī)選型計(jì)算。
并繪制工作面布置圖,三機(jī)配套圖,通風(fēng)設(shè)備布置圖,帶式輸送機(jī)施工圖。



關(guān)鍵詞:礦井機(jī)械化;選型設(shè)計(jì);設(shè)備配套;運(yùn)輸提升;通風(fēng)排水




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 design requirements issues, the design mainly from the mine location, Ida trend, roof and floor conditions, hydrogeology, mine development system, ventilation and drainage requirements, the main shaft system, the main transport systems of basic conditions of mine, for mining machine selection calculation, selection of emulsion pumping station hydraulic support selection calculation, scraper conveyor selection calculation, calculation of ventilation equipment selection, equipment selection drainage calculations, selection of belt conveyor calculation, the main shaft hoisting equipment selection Computing. And the mapping of Figure 3, and machinery, pump house floor plan, main shaft hoisting equipment, electric control plan.

Key words:
shearer; conveyor; belt conveyor; drainage and ventilation; hydraulic support; mine hoist
