Decommissioning planning for Saskatchewan's potash mines

, 2004
Saskatchewan's potash producing companies are now in the process of developing decommissioning and reclamation (D&R) plans for potash mines which were in operation many years before these plans were required by provincial regulations.

Seismic Measurements by the u.s. Geological Survey During the Pre-Gnome High-Explosives Tests Near Carlsbad, New Mexico. Final Report [PDF]

, 1960
The U. S. Geological Survey monitored three highexplosive test shots at the Gnome site during the PreGnome experiments and monitored routine blasting in the potash mine of the Duval Sulphur and Potash Company. The motion in the potash mines near Carlsbad

Detection‐Dog‐Guided Camera Placement Increases Efficiency of Surveys for Long‐Tailed Weasels (Neogale frenata) 利用探测犬引导布设相机可提升长尾鼬调查效率

Wildlife Letters, EarlyView.
By comparing widespread surveys with randomly placed cameras to a protocol pairing detection dogs with cameras, we found that the detection‐dog‐guided camera survey had approximately 33 times greater detections with fewer camera nights and reduced survey costs. We recommend using detection dogs to identify areas to focus camera trapping. ABSTRACT Multi‐

Hidden in the Glaze: Cobalt Blue Decorations of Catalan Tin‐Glazed Ceramics From the 16th to 18th Centuries

Archaeometry, EarlyView.
ABSTRACT This study investigates technological evolution in 16th–18th century Catalan tin glazes and cobalt blue decorations. Analysis reveals three glaze strategies, highlighting shifts in tin oxide use and cobalt pigment composition. In the 16th century, tin oxide acted as an opacifier and cobalt pigments exhibit low arsenic content with CoO/NiO and ...

Thermal processes in the atmosphere of the working space of a combine operator at a deep potash mine with local air conditioning

Известия Томского политехнического университета: Инжиниринг георесурсов
Mining operations in conditions of great depths are characterized by high temperatures of the rock mass. As a result, mining enterprises are faced with the problem of high air temperatures in working areas, which is a violation of the requirements of ...

Without Scratching the Surface: Depth Profiling Compositional Muon Analysis of Ancient Faience From Egypt and Sudan

Archaeometry, EarlyView.
ABSTRACT The specific depth‐profiling capabilities of the muonic x‐ray emission spectroscopy (μ‐XES) technique have proved to be effective for examination of the elemental distribution within ancient coins. This ‘layered’ analysis can also be applied to the examination of ancient faience, the production of which can result in distinct layers (glaze ...

Potash recovery from process and waste brines by solar evaporation and flotation [PDF]

"The Bureau of Mines investigated energy-efficient methods for recovering potash values from process and waste brines. Laboratory pan evaporation of four chloride brines produced crude salts containing predominantly sylvite, halite, and carnallite.
