石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)是具有高硬度、高脆(cui)性特點的(de)材(cai)(cai)(cai)(cai)(cai)料(liao)。隨著科學技術(shu)和現代工(gong)業的(de)發(fa)展(zhan)，石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)的(de)應用(yong)領域日益擴展(zhan)，石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)開采(cai)量(liang)(liang)逐年(nian)增(zeng)(zeng)加，如(ru)圖1—1所示。我國石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)行業經過近20年(nian)的(de)高速發(fa)展(zhan)，一(yi)躍成(cheng)(cheng)為在石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)產(chan)(chan)量(liang)(liang)、消費量(liang)(liang)、貿易量(liang)(liang)均(jun)位(wei)于世(shi)界(jie)首(shou)位(wei)的(de)石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)工(gong)業大(da)國。2008年(nian)石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)產(chan)(chan)量(liang)(liang)達2．23億平方千米(mi)，比2007年(nian)同比增(zeng)(zeng)加了27%。2005年(nian)以來(lai)，石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)的(de)產(chan)(chan)量(liang)(liang)以穩定(ding)的(de)速度增(zeng)(zeng)長，其(qi)產(chan)(chan)品(pin)、工(gong)藝、設備(bei)技術(shu)含量(liang)(liang)極大(da)提高，大(da)中型石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)企業不斷涌現，行業呈現強勁的(de)發(fa)展(zhan)勢(shi)頭，中國已成(cheng)(cheng)為名副其(qi)實的(de)世(shi)界(jie)石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)加工(gong)廠(chang)，重慶石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)加工(gong)發(fa)展(zhan)趨勢(shi)和前景看好。近年(nian)來(lai)中國作(zuo)為石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)開采(cai)和加工(gong)的(de)領頭國，生產(chan)(chan)240個(ge)品(pin)種的(de)花(hua)崗石(shi)(shi)，石(shi)(shi)材(cai)(cai)(cai)(cai)(cai)總產(chan)(chan)量(liang)(liang)約(yue)占世(shi)界(jie)的(de)65%。
