The European Union’s climate policy and the assumptions of Green Deal require Poland to take decisive transition efforts. achievement neutrality is a challenge due special role coal in Polish economy. Closing mines abandoning greatest for local communities mining regions. This article presents example Wałbrzych, post-mining town, which has been experiencing accumulation negative consequences in...
– The final result of the project is to create a 2D model mine plan based on results geophysical measurements. ERT was chosen as primary method in this due fact that voids and air have very high resistivity (3,3 ∙ 1016Ωm). Voids are well recognizable results. Using Seismic Refraction Tomography (SRT) planned some profiles. SRT rarely used archaeogeophysical research.
Oil sands surface mining in Alberta has generated over a billion cubic metres of waste, known as tailings, consisting sands, silts, clays, and process-affected water that contains toxic organic compounds chemical constituents. All these tailings will eventually be reclaimed integrated into one two types mine closure landforms: end pit lakes (EPLs) or terrestrial landforms with wetland feature. ...
This paper will propose a whole new viewpoint about building a CSPMS(Coal-mine Safety Production Management System) by means of information technology. This system whose core part is a four-grade automatic triggered warning system achieves the goal that information transmission will be smooth, nondestructive and in time. At the same time, the system provides a comprehensive and collective techn...
The Oriental region, in Morocco, is surrounded by the Algerian border to East, Atlas West, Mediterranean North and desert south. This region has benefited from intense mining activity that played an important role national economy. intensification of Touissit Sidi-Boubker mines left behind closure tons waste shelter without a plan conservation. These mine storage sites still contain very high l...
Drainage from metal-sulphide rich rocks may cause considerable environmental stress in the form of elevated sulphate and heavy metal contamination of the environment. Mine draining effects from closed mines may be abated using indigenous and introduced microbial communities for sulphate reduction and metal precipitation at the mining site. Here we characterized the general and sulphate reducing...
