19、部門中主要用來(lái)運(yùn)送大量散狀貨物，如礦石、煤、砂等粉、塊狀物和包裝好的成件物品。帶式輸送機(jī)是煤礦最理想的高效連續(xù)運(yùn)輸設(shè)備，與其他運(yùn)輸設(shè)備相比，不僅具有長(zhǎng)距離、大運(yùn)量、連續(xù)輸送等優(yōu)點(diǎn)，而且運(yùn)行可靠,易于實(shí)現(xiàn)自動(dòng)化、集中化控制,特別是對(duì)高產(chǎn)高效礦井，帶式輸送機(jī)已成為煤炭高效開(kāi)采機(jī)電一體化技術(shù)與裝備的關(guān)鍵設(shè)備。特別是近10年，長(zhǎng)距離、大運(yùn)量、高速度的帶式輸送機(jī)的出現(xiàn)，使其在礦山建設(shè)的井下巷道、礦井地表運(yùn)輸系統(tǒng)及露天采礦場(chǎng)、選礦廠中的應(yīng)用又得到進(jìn)
