    The behaviour of mine tailings during hydraulic deposition by G. E. BLlGHT*. Pr.Eng.. Ph.D.. D.Sc.(Eng.). F.S.A.I.C.E. and G. M. BENTELt. M.Sc.(Eng.). Grad. S.A.I.C.E. SYNOPSIS The environmentally acceptable disposal of fine-particled mining and industrial wastes by the formltion of hydraul- ic-fill slimes dams is becoming an increasingly important aspect of the total mining endeavour. Relatively little is known of the behaviour of waste slurries during deposition. This paper describes and analyses the following aspects of slurry behaviour: (i) the relationship between viscosity, shear strength, and water content, (ii) the slope assumed by a thickened slurry, (iii) particle-size sorting on a hydraulic-fill beach, (iv) gradients of hydraulic-fill beaches, and (v) internal erosion during the deposition of slurry. SAMEVATTING Die wegdoening van mynbou- en nywerheidsafval met bale fyn partikels deur die vorming van hidroulies gevulde slykdamme, wat vir die omgewing aanvaarbaar is, word 'n al hoe belangriker aspek van die totale mynboupoging. Dur is betreklik min bekend oor die gedrag van afvalflodders tydens afsetting. Hierdie referaat beskryf en ontleed die volgende aspekte van die gedrag van flodder: (i) die verhouding tussen viskositeit, skuifsterkte en waterinhoud, (ii) die helling wat 'n verdikte flodder inneem, (iii) partikelgroottesortering op 'n hidroulies gevulde strand, (iv) gradient van hidroulies gevulde strande, en (v) inwendige erosie tydens die afsetting van flodder.

  • Pathogens and Biosolids SCHOOL of PLANT and ENVIRONMENTAL SCIENCES, VIRGINIA TECH
    Pathogens and Biosolids SCHOOL OF PLANT AND ENVIRONMENTAL SCIENCES, VIRGINIA TECH By: Michael Badzmierowski and Dr. Gregory Evanylo Pathogens are disease-causing microorganisms that include bacteria, viruses, protozoa, and helminths (parasitic worms). Pathogens can present a public health hazard if they are transferred to food crops grown on land to which biosolids are applied; contained in runoff to surface waters or in leachate to groundwater from land application sites; or transported away from the site by vectors such as insects, rodents, and birds. For this reason, federal and state regulations specify pathogen and vector attraction reduction requirements that must be met by biosolids applied to land. Lists of pathogens that can be found in untreated sewage sludge and the diseases or symptoms that they can cause have been extensively documented (U.S. EPA, 1995; U.S. EPA, 2003; Compost Science & Utilization, 2005; Sidhu and Toze. 2009). In 1993, the U.S. EPA implemented regulations entitled “The Standards for the Use or Disposal of Sewage Sludge” (U.S. EPA, 1993). These regulations, promulgated as 40 CFR (Title 40, Code of Federal Regulations), Part 503 Biosolids Rule (Part 503 Rule), were established to protect public health and the environment from adverse effects of pollutants and pathogens in biosolids. The 503 Rule specifies minimum federal regulations for pathogen and vector attraction reduction requirements that must be met by biosolids applied to land. Currently, the only pathogens regulated are fecal coliform, Salmonella spp., enteric viruses, and helminths. This group of pathogens are known as indicator microorganisms, as they can indicate the presence of a larger set of pathogens.

All roads and streets serve for purposes of intercommu- nication and traffic; city streets, however, are planned with the further object of providing light and air to the adjacent houses, and, incidentally, are utilized as receptacles for a network of underground pipes, conduits and wires which afford drainage and sewerage facilities and furnish water, gas, heat, light, steam and electric power, etc., to the build- inks. When we demand--even of our country roads--that they should not be dusty in dry weather, nor muddy and impassable in wet seasons, it is Obvious that city streets, in which our habitations, offices and places of work are located, should be subject to much stricter requirements. We are, as far as this paper is concerned, interested chiefly in the sanitary aspects of street construction or the paving of its surface. The essential requirements of a good city street pavement are quick surface drainage, good founda- tions, impermeability and hardness of surface, avoidance of slipperiness, least resistance to traffic, cleanliness and noise- lessness. Impermeability and noiselessness are the chief desiderata, from a sanitary point of view. There is plenty of medical testimony available tending to prove that the ceaseless noise, from early morning till late at night, due to vehicles passing over rough stone pavements, affects the nervous system and reduces the duration of life.
