Abstract

A building, packing or filling material, pref. for use in underground mining, is claimed (I), contg. a plastic component consisting of plastic residues or waste plastic (II). Also claimed are processes for the prodn. of (I), the disposal of carbon-rich slag from incinerators, the prepn. of (II) for transport, the prodn. and pretreatment of (II), and the prepn. and purification of components of (I). Also claimed is a binder for a pref. form of (I), contg. MgO and the MgCl2-contg. spent liq. from a potash and salt mine. (I) is produced by shredding the waste plastic (II) until it is able to absorb the spent liq. (III) from a potash or salt mine, then mixing it with (III) and the binder (IV) from a flue gas purificn. plant. Carbon-rich slag from incinerators is disposed of by combining with chloride-rich residues from the mine. The partly impure plastic (II) is milled and treated with chemicals, esp. lime with a low surface moisture content, until no more gas is evolved and the static charge is eliminated. A process for the treatment of (II) comprises washing with a liq. with pH greater than 12. A magnesia binder for (I) is prepd. by mixing the MgCl2-contg. spent liq. from a potash and salt mine with MgO. (II) is produced from waste plastic by heating to make it inert and convert it into a foam. A process for the disposal of (II) comprises making it inert, pelletising or granulating it and using it to fill water-bearing cavities. A process for the prepn. and purification of (II) comprises addn. of an alkaline component (IV) before and/or during the prepn. and granulation process, which combines with added moisture to dissolve amphoteric metallic impurities.

Description

In der Patentanmeldung P 43 13 706.7 wird ein für die untertägige Hohlraumverfüllung entwickeltes Versatz­ material aus recycleten Kunststoffgranalien als Zuschlag und einer Bindekomponente aus Magnesiabinder beschrieben, das durch Zusatz von quellfähigem, vorwiegend kaolini­ tischem Ton einen aus diesem Baustoff hergestellten Baukörper wirksam gegen eindringende saure Grubenwässer abzudichten vermag.In patent application P 43 13 706.7 one for underground cavity backfill developed offset material made from recycled plastic granules as a surcharge and a binding component made of magnesia binder, by adding swellable, mainly kaolini table clay made from this building material Structure effective against penetrating acid mine water can seal.

Weiterhin wurde in der Zusatzpatentanmeldung P 43 16 418.8 gefunden, daß bei Verwendung einer hydraulischen Bindung aus Zement anstelle des Magnesiabinders der Tonzusatz auch hier eine vergleichbare abdichtende Wirkung gegen ein­ dringende saure Grubenwässer auf den abgebundenen Bau­ körper besitzt und diesen so wirksam gegen einen chemischen Angriff zu schützen imstande ist.Furthermore, in the additional patent application P 43 16 418.8 found that when using a hydraulic binding the clay addition also made of cement instead of magnesia binder here a comparable sealing effect against urgent acid mine water on the hardened building owns the body and is so effective against a chemical Is able to protect attack.

Darüber hinaus hat sich ferner herausgestellt, daß die für die Gebirgsmechanik erforderlichen elastischen und plasti­ schen Deformationseigenschaften des Baukörpers besonders günstig sind, wenn das als Zuschlag verwendete Kunst­ stoffgranulat eine Korngröße kleiner 1 mm besitzt.In addition, it has been found that the for the mountain mechanics required elastic and plasti the deformation properties of the structure in particular  are cheap if the art used as a surcharge granulate has a grain size of less than 1 mm.
