style="text-indent:25px">礦山機(jī)械行業(yè)首先存在的問題：一是礦山機(jī)械行業(yè)企業(yè)綜合實(shí)力不強(qiáng)，大多數(shù)企業(yè)在科研、新產(chǎn)品開發(fā)、技術(shù)改造和企業(yè)管理等方面的精力和資金投入方面都處于停滯狀態(tài)。國內(nèi)礦山機(jī)械的產(chǎn)品尤其是國家建設(shè)急需的關(guān)鍵設(shè)備不能滿足要求，義烏礦山機(jī)械鑄造，而且存在產(chǎn)品技術(shù)含量低、產(chǎn)品附加值不高、產(chǎn)品質(zhì)量不穩(wěn)定、全員勞動(dòng)生產(chǎn)率低等問題，造成我國礦山機(jī)械制造企業(yè)的產(chǎn)值增長率與利潤增長率極不相稱。二是產(chǎn)品的品種、技術(shù)、質(zhì)量、服務(wù)等方面存在問題，導(dǎo)致國內(nèi)礦山機(jī)械行業(yè)對礦山的實(shí)際貢獻(xiàn)率低。以冶金礦山為例，目前在用的設(shè)備有1180種，我國能自給的只有26%左右，而且大都還是技術(shù)含量低和質(zhì)量要求不高的設(shè)備，義烏礦山機(jī)械鑄造，其余74%左右仍然需要進(jìn)口，義烏礦山機(jī)械鑄造。國產(chǎn)設(shè)備尤其是技術(shù)含量高的移動(dòng)設(shè)備，如全斷面掘進(jìn)機(jī)、礦用汽車、挖掘機(jī)、鏟運(yùn)機(jī)等，與進(jìn)口設(shè)備相比還有較大差距。礦山機(jī)械設(shè)備采用長壽命、低能耗及減輕重量的設(shè)計(jì)原則。義烏礦山機(jī)械鑄造</p><div
