    摘要： The invention relates to a process for facilitating the disposal of flowable and pumpable working fluids based on emulsifiers containing W/O invert emulsions--more particularly corresponding auxiliaries of the type used in geological exploration, such as oil-based w/o invert drilling muds--and for the simplified cleaning of solid surfaces soiled therewith, if desired using flowable spraying aids, the process being characterized in that, by selecting and adapting the emulsifiers/emulsifier systems to the oil phase of the invert emulsion, temperature-controlled phase inversion is achieved at temperatures below the in-use temperatures of the w/o invert emulsions, but above the freezing point of the aqueous phase and in that disposal and cleaning are carried out at temperatures in and/or below the phase inversion temperature range. The invention also relates to the use of this process for the cleaning and disposal of roc cuttings covered with residual drilling mud from geological exploration during and/or preferably before their on-shore or off-shore dumping

    摘要： The invention relates to the use of at least predominantly linear hydrocarbon compounds olefinically unsaturated in the alpha-position with flashpoints of at least about 80.degree. as the oil phase or as part of the oil phase of oil- or water-based free-flowing borehole servicing preparations. Particular significance is attributed to corresponding drilling fluids which, together with the alpha-olefins, contain other oil phases from the field of borehole servicing preparations and are distinguished by ecological compatibility, being degradable under both aerobic and anaerobic conditions. Suitable mixture components for the oil phase are, in particular, oleophilic alcohols, ethers and corresponding esters selected from carboxylic acid esters and/or carbonic acid esters.

    摘要： A process is described for rock consolidation, e.g. in tunnel construction and mining, by injection of aqueous preparations of melamine resin condensates and/or urea formaldehyde condensates together with an acid curing agent. The process is characterized by the use of aqueous solutions of hydrogen sulfate salts, especially solutions of alkali and/or ammonium bisulfates, as curing agents. The curing agent solutions can contain additional auxiliary agents and active substances such as corrosion inhibitors, structurizers and adhesion agents. Preferred resin solutions for consolidation with these aqueous curing agents contain added zeolite NaA and/or hydrosodalite for increasing their serviceability, and especially for prolonging their storage life.
