Yelimestone ilitye watyunyuzwa ngenxa umsebenzi wokwakha

Yelimestone igrabile ezisetyenziswa imisebenzi kokugqiba, kwakunye ekuvelisweni izichumisi izimbiwa kunye lime. izinto ezisebenzayo eziveliswa ityumza yaye sieving engxondorheni ngakumbi, nto leyo lekalika.

incazelo jikelele

Ezibiza kakhulu kwaye inkunkuma kukuba umgangatho leyo ifunyenwe ukuhluzwa iliwa ukuba carbonate calcium. ukungcola kunye nezongezelelo ezahlukeneyo ukunciphisa umgangatho iimpawu lwelimestone ingqushu luncedo. Le nto ayikho ixesha elide kakhulu, kodwa iimpawu ezifana neendleko eziphantsi, ukumelana iqabaka, kwakunye ukhuseleko lokusingqongileyo, yenza kakhulu ukukhuphisana ukuba umsebenzi wokwakha eziphathekayo.

iimpawu technical

uhlalutye lekalika enokumelana ebalaseleyo zizothuso thermal, esibonakala ngamandla elungileyo, nasisisa njengento indalo. Frost bokuxhathisa kwaye namanzi nokufunxwa yimiwewe zikwinqanaba eliphezulu. Ukuba inombolo kunye ipesenti ubumdaka esezantsi, impahla iye esintsundu bubomvu okanye ithinti omthubi. Xa kuthelekiswa ne lenyengane, yelimestone uhlalutye oko radioactivity ephantsi adhesion eliphezulu. Ekugqibeleni dolomite zingafumaneka leyo uneempawu okuphuma amandla aphezulu. Kaninzi oku kuthelekiswa amaqhekeza lenyengane yaye ngokwesiseko loxinano isambuku. iintlobo lekalika iye ratio ngaphantsi isambuku eliphantsi. Oku kunceda ekunciphiseni ukusetyenziswa kwayo. Ixabiso izinto ezinjalo usezantsi kakhulu xa kuthelekiswa iimveliso efanayo kwezinye iintlobo kunye izinto.

iipropati key

uhlalutye lekalika na iintlobo eziliqela. Njengoko izenzo kakhulu ezifanelekileyo cuboid, isalathiso flakiness yena kwisithuba-10%. Umxube izinto ezinjalo kakhulu izi- mgodini, oku kubonisa umlinganiselo eliphantsi flow yezisombululo yokubopha. Lolo lisetyenziswa njengelitye zokuhombisa ngexesha ukwakhiwa kweendlela, leyo ayiyi kuba umthwalo umxhelo. Ukuxinana kwezinto ayidluli 80 MPA. ukuqina kwayo iqabaka phezulu ngokwaneleyo, loo nto inkunkuma ekwaziyo kwazo ukuya ku-125 imijikelo nobudlelwane kunye zibambene. ukufakwa Amanzi yahluka ukusuka ku 1 ukuya ku 2.2%. Ukuba sithethe wearability, oku kulingana ngexabiso kumda ka 0.3-0.8 grams sentimitha square kilometre. Mfanelo ebalulekileyo ubunzima ethile kwaye ukususela 1260 ukuya ngeekhilogram 1320 nge-cubic meter.

enkwalini

Ukuze kuveliswe yelimestone ingqushu ukwakha, kuyimfuneko ukufumana na. Iidipozithi ezininzi eziphathekayo, ngenxa yesi sizathu, kusilungele ngokwezoqoqosho ukuze bafumane emifanekisweni eqingqiweyo ezingqongileyo. Mining lwenziwa oluvulekileyo noncedo okanye ngenxaso, emva ukuqhumisa encinane. Kwinqanaba elilandelayo, kulayishwa rocks kunye excavator, a ngokobuninzi ezinkulu kungena kumatshini obukhulu. Kunye nemeko encinane iqhekeza sieving kwenzeka ngokusebenzisa ngesihlungulo okhethekileyo. yokhuselo kunye nokuhlela eminye amaqhezu afanelekileyo ziyaphunyezwa ukwahlula iindawo kwi "igquma" unako ukukhonza ngumzekelo nje. Emva koko, lo eziphathekayo zingafumaneka, into enokuba iqhekeza elincinane, eliphakathi okanye irhabaxa. Xa yokulungisa izixhobo mihla ekuvumela ukuba ukuchaza ububanzi kwaye usebenzise.

isicelo

Ekuvelisweni umbandela ochazwe utsaleleka ukuba GOST, lekalika otyunyuziweyo zingasetyenziswa zokwenza imisebenzi eyahlukeneyo. Xa kuziwa krupnofraktsionnyh izinto, zisetyenziswa ngexesha nokwakhiwa kweendlela. Kanti amancinci okanye medium ngaphezulu efanelekileyo ukuba inkunkuma ye umphantsi nomphezulu kweendlela okanye ilungiselelo kweemveliso eziphathekayo. Phambi kokuba uthenge into kubalulekile ukuba uwazi iziqinisekiso ezifanelekileyo kunye nemimiselo, leyo wayenza yacaca iimpawu ezisemgangathweni kunye nokuthembeka eziphathekayo. Phambi kokuba uthenge i Nyengane nakhandiweyo, lekalika, iingcali ukucebisa ukunikela ingqalelo ubuthi yayo. Nakuba kunjalo, ukuba phambi kwakho izinto ezikumgangatho ophezulu, eli nani kuya kuba phantsi kakhulu, nto leyo ebonisa ukuba eziphilayo kunye nokhuseleko.

Ukusetyenziswa iinxalenye ezahlukeneyo zegrabile

lekalika Ekhathazekile (GOST 8267-93) ukuze amaqhezu ezahlukeneyo. Xa kufikwa ubungakanani ezakha milimitha-5 ukuya ku-20 phambi kwakho izinto womsizi. Oku kusetyenziswa ekwenziweni ukuhlanganiswa eziphathekayo. zilungiso eziphathekayo oversized badla ezenziweyo usebenzisa le njengamasuntsu iqhekeza lekalika. Luphawu kusetyenziswa ezi izixhobo ingaphakathi izakhiwo, kwakunye nokwenziwa kwekalika. Ekhathazekile leyo iqhezu isusela ukusuka milimitha-20 ukuya ku-40, isetyenziswa kakhulu rhoqo xa kuthelekiswa nezinye izinto eziphilayo. Njengoko intsimi engundoqo ukusetyenziswa igagasi obuxhasa isiseko, phakathi kwezinye izinto, oku kuthatha yonke into amaqonga namaculo, emva ephilisa ukufumana nenkangeleko esinomfaneleko elide nokugcina iimpawu zayo esemgangathweni. Eyona ndlela iphambili izinto izenzo nokuveliswa izakhiwo ufakelo lwesamente kunye nokwakhiwa kweendlela, izinto ezisetyenziswa zibethwa obukhulu.

Isicelo krupnofraktsionnogo inkunkuma

Ukuba iziqalelo ezibonakalayo imilinganiselo ku ezahlukene milimitha-40 ukuya kuma-70, oko kubonisa ukuba kusetyenziswa kungeyonto ayenza rhoqo. Le ulwalathiso esisiseko - a zokulinganisa inwebu zegrabile okanye namalungiselelo pillows. Lidla enqabile xa ebonakalayo iqhekeza esetyenziselwa olungaphambili khazi. Oku kuyinyaniso kwiiprojekthi ezinkulu kuphela.

Ngoko ke, i zithandwa kakhulu ezi yamatye iqhezu ephakathi. Kusebenza kukho izinto zokwakha oyimfuneko owenziwa na iimpawu ezigqwesileyo ezibophelelayo i lokufaka obalaseleyo. Phakathi iimpawu zayo zingahlukaniswa nokumelana ebandayo, kwakunye namandla esiphezulu ovumela kwaziswa ukuba zisebenze kwimozulu akulinikwanga kunye notshintsho ngesiquphe kwamaqondo obushushu nokufuma.

Bendlela kunye nobuthathaka

Phambi kokuba uthenge amaqhekeza yelimestone M600, kufuneka uwazi onke amandla kunye nobuthathaka kule nto. Okokuqala, kufuneka kukhunjulwe ukuba olu hlobo zegrabile ayikho elide xa kuthelekiswa luhlalu. Noko ke, kule bawo kuphela. Ngenxa yokuba ukhuseleko, isetyenziselwa ukwakhiwa kwezakhiwo ezahlukahlukeneyo kunye nezindlu nenjongo zokuhlala ngempumelelo. Mining wenziwa lula ngakumbi xa kuthelekiswa izinto ezifanayo, oku kunempembelelo entle iindleko. Yelimestone inkunkuma iye amandla aphantsi, nto leyo esisizathu sokuba ukusetyenziswa kwayo ekwakhiweni kwezakhiwo ezinkulu alilungile, akusoloko lula. Nangona kunjalo, oku ngokupheleleyo libonisa yokusebenza okusemandleni alo ekuvelisweni izakheko ezomeleleyo eziphathekayo ngobukhulu ezincinane.
