    Mining in Mongolia

    This is only preliminary moves in what will become a multi billion $$$ lawsuit but if there is more than a grain of truth in these allegations it will behoove all interested parties to be really doubtful about QA/QC on all chinese steel products. Redpath is a worldclass mining...

    Changing original residential furnace motor to a Genteq hi efficiency unit

    Been researching this matter for some time. Have learnt that a Genteq 6005 would be a suitable change out unit. The installation instructions are definitely a bit involved for someone electrically challenged like myself. Can anyone here provide advice or comments that I should be aware of???

    Hotel failure in China

    Looks like another structural failure altho I doubt the media will provide much engineering data since in the existing bigger picture , a few deaths will be insignificant. Building appears to be less than 2 years old...

    And yet another mining dam failure......

    I doubt that this will get as much attention as recent failures in Brazil, but it proves that this is an issue that has has no national boundaries https://www.bbc.com/news/world-europe-50108413

    Global warming is over!!!

    Dont know if this is fake news or a legitimate article. Regardless, this is the first time Ive seen this suggested and at the very least , I believe the idea needs wider dissemination , if only to generate discussion...

    Canadian Flooding

    Unless one defines a 104 year old structure that was nominally designed for a 1 in 1000 year flood event to be poorly designed, then this is not specifically an engineering failure. However the same area flooded significantly in 2017. In western Canada in 2013 , Calgary was...

    Headlight bulbs

    I dont want to go to HIDs or LEDs. Most knowledgeable people accept that the H7 uprades come at the expense of shortened life span. Has anyone identified the sweet spot where one is not changing bulbs every 4-6 months???

    Maybe not an engineering disaster

    but surely a prime example why we all might want to avoid chinese products. Their business ethics and attitude toward basic safety, workers rights etc etc leaves a lot to be desired https://news.yahoo.com/overloaded-faulty-vehicle-led-deadly-054158869.html

    Demise of coal mining

    I doubt that this thread will develop much interest but I was kinda glad to see this article..... at least someone is thinking about the social costs endured by the victims of environmentalists. https://www.ft.com/content/d820cd62-c883-11e8-86e6-19f5b7134d1c

    Concrete without Sand???

    Has anyone ever produced adequate concrete without the use of sand?? Not so hypothetically, assume local sources of sand are unavailable for environmental reasons, could a guy crush the local granite sufficiently small so as to produce not only the required aggregate but also the necessary...

    Developing QA/QC Documentation.

    As a senior project manager I am aware of the generalities of modern QA/QC practice. However until now I have always had experienced QA/QC personnel available... not only to do the physical inspections and audits, but also to prepare the initial processes and procedures. I am now in a position...

    Furnace Fan Efficiency??

    I am the first to admit that this is a rather trivial query, but does anyone know the typical electrical fan efficiency of a regular North American furnace fan. ?? I am not seeking anything on the thermal efficiency of the furnace system , just the blower fan. Since these are relatively low...

    Dropping Concrete 5000 metres vertically

    I apologise for the double post but I'm not sure whether a mining or a civil guy is more likely to be able to help me. This is I believe a regular task in mining but very specialised for civil, and there is sopmething happening here way outside my area of mining expertise. I'm presently having...

Ive got some extremely comptetant people working on different mix designs and various additives but the question has been raised whether its possible to modify our concrte...
