Parizvino, China inonyanya kutarisisa kuchengetedzwa kwezvakatipoteredza uye kuchengetedza simba. Panyaya yekushandiswa kwakadzika kwezviwanikwa zvemarasha, vatengi vazhinji havazivi kuti ndeipi iri nani pakusarudza marasha akakuyiwa chigayo chinotenderera chakamira uye chigayo chebhora chemarasha akakuyiwa. Munyaya inotevera, HCM yakaongorora hunhu hwemarasha, izvo zvinobatsira mutengi kusarudza chigayo chekukuya marasha.

HLMmarasha akakuyiwa chigayo chinotenderera chakamira 

1. Nekuda kwekusiyana kwemhando yemagadzirirwo emalahle uye bhaira rinoshandiswa, zvinodiwa zvehukuru hwezvimedu zvemarasha zvakasiyana. Kazhinji, chiyero chekuongorora chinosvika 90% pa 200 meshes. Midziyo yekukuya inofanira kukwanisa kugadzirisa hutete hwayo;

2. Kazhinji, mabhuroko emarasha haasi zvinhu zvakaoma zvakanyanya. Kazhinji, marasha ane hunyoro hunopfuura 15%, uye lignite inosvika 45%. Saka, michina yekupwanya marasha inofanira kukwanisa kuenderana nezvinhu zvine hunyoro hwakawanda uye kuomesa zvinhu panguva yekukuya. Hazvidikanwi kugadzira imwe dryer kuti uwedzere maitiro ekuomesa;

3. Marasha ane mvura inobvira moto, uye marasha pachawo anogona kutsva, saka matanho anodzivirira moto uye anodzivirira kuputika anofanira kutorwa panguva yekukuya;

4. Marasha ane tsvina yakaoma uye yakaoma kukuya, iyo inodiwa kuti ienderane netsvina yakaoma uye yakaoma kukuya panguva yekukuya;

Chigayo chebhora kanamarasha akakuyiwachigayo chinotenderera chakamiraKugadzirira marasha akapwanywa? Kunyangwe zvese zviri zviviri chigayo chemarasha chakapwanywa chakatenderera uye chigayo chebhora zvichigona kugadzirisa marasha zvakadzama, kubva mukuongororwa kwehunhu hwemarasha, chigayo chemarasha chakatenderera chakatenderera chakakodzera nekuda kwezvikonzero zvitatu:

Chekutanga, chigayo chemarasha chakapwanywa chinoshandisa nzira dzakasiyana dzekugadzira nekugadzira, icho chinotora nzvimbo diki, chine guruva shoma uye ruzha rushoma panguva yekugadzira, uye chinogadzira marasha akapwanywa ane giredhi repamusoro uye mashandiro akanaka ekupisa.

Chechipiri, zvichienzaniswa nebhora remuchina wesimbi wechiyero chimwe chete, simba rinoshandiswa nemuchina wesimbi ...

Chechitatu, chigayo chemarasha chakapwanywa chinobatanidza maitiro mashanu ekupwanya, kukuya, kuomesa, kusarudza hupfu uye kutakurwa. Maitiro acho ari nyore, marongerwo acho akatetepa, nzvimbo yepasi inenge 60-70% yehurongwa hwekugadzira bhora, uye nzvimbo yekuvaka inenge 50-60% yehurongwa hwekugadzira bhora.

Chinhu chikuru ndechekuti chigayo chemarasha chakapwanywa chakamirainoshandisa muchina unosimbisa hupfu unoshanda nesimba, une hupfu hwakawanda hunoshanda uye nzvimbo huru yekugadzirisa. Hupfu hwakatsetseka hunogona kusvika pasi pe3% ye 0.08 mm sefa remarasha, izvo zvinogona kusangana nezvinodiwa zvekukuya marasha kana anthracite mumutsara wekugadzira simende.
