Ash management

DIAMO, state enterprise, branch HBZS, offers ash producers the possibility of continuous collection of ash with the provision of a comprehensive service, i. e. collection, transport and utilization in accordance with applicable legislation.

We ensure the use of ash in the following way:

• continuous collection of ash from the production of heating and power plant sources for use in the mines of OKD, a.s., or DIAMO, s. e.

We operate 8 facilities for utilization of waste with catalogue numbers 100101, 100102 and 100105 for the production of certified products (backfill material). The backfill mix is used for explosion-proof closure of mine workings, filling of open spaces, prevention or repression of steaming up of coal.

• collection of ashes from the production of heating and power plant sources with use on the surface for remediation and reclamation of the area
• collection of ashes for the production of strenghtened backfill materials intended for the liquidation of main mining works

Cement ash mixtures with cubic compressive strength of 2 or 5 MPa after 28 days.

• fly ash binder for the production of hydraulic road binder
