1、采煤機(jī)煤巖識(shí)別系統(tǒng)設(shè)計(jì)這是一份很完整的優(yōu)秀設(shè)計(jì)，歡迎下載！正文共 70 頁(yè)，字?jǐn)?shù)總計(jì)：28985摘要煤炭作為當(dāng)今社會(huì)最主要的能源之一，其重要性不言而喻。雖然現(xiàn)在由于過(guò)度開(kāi)采，大家開(kāi)始更多的關(guān)注新能源，并且也取得了令人喜悅的成果。但是煤炭仍將會(huì)是目前乃至未來(lái)相當(dāng)長(zhǎng)一段時(shí)間的主要能源之一。同時(shí)更是我國(guó)的主要能源之一。所以，也就奠定了煤炭行業(yè)成為我國(guó)重要經(jīng)濟(jì)支柱的原因之一。所以我們必須認(rèn)識(shí)到煤炭的機(jī)械化開(kāi)采和掘進(jìn)是提高煤炭產(chǎn)量、提高煤炭生產(chǎn)經(jīng)

2、濟(jì)效益和社會(huì)效益的根本保障。而采煤機(jī)作為煤炭機(jī)械化生產(chǎn)的十分重要的設(shè)備之一，他的機(jī)械化進(jìn)展對(duì)于我國(guó)煤炭開(kāi)采的機(jī)械化進(jìn)展必將起到至關(guān)重要的作用。為了實(shí)現(xiàn)無(wú)人工作面采煤機(jī)滾筒的自動(dòng)調(diào)高，需要解決煤巖界面自動(dòng)識(shí)別技術(shù)。本文分析了當(dāng)前國(guó)際和國(guó)內(nèi)的煤巖識(shí)別技術(shù)，就這一背景下提出了一種新的、基于滾筒采煤機(jī)減速器惰輪軸受力分析的綜合煤巖識(shí)別方法。我們通過(guò)采集采煤機(jī)惰輪軸在開(kāi)采不同硬度的煤巖時(shí)的受力，并根據(jù)當(dāng)?shù)氐木唧w情況進(jìn)行分析，從而實(shí)現(xiàn)了采煤機(jī)的無(wú)人
