Introduction There are two key techniques for transport of raw materials in the surface mining in Poland: continuous via belt conveyors and cyclic via heavy trucks.
The results can also be used as supplementary materials in the procedure for obtaining an environmental decision.

Conventional extraction of BFRs from polymeric materials is usually performed by Soxhlet extraction, which requires long extraction time and high solvent consumption [3].
Nevertheless, these advanced solvent extraction techniques means high energy cost and equipment requirement, which have become challenges faced by them to recycle BFRs from polymeric materials [15].
Experimental section Materials.
Standard stock solution of bromine ion (1000 mg/L) was purchased from the National Research Center for Certified Reference Materials of China and TBBPA (≥97% purity) was supplied by ACROS Ltd., and anhydrous sodium sulfate (Na2SO4) was analytical reagent from domestic manufacturers.

Predicting failure in composite materials is complicated due to the multiplicity of failure modes involving either fibres or the matrix or combinations of both [6].
Tsai Hill's criterion is based on the Von Mises distortional energy criterion which was modified by Hill so as to satisfy anisotropic materials and was subsequently applied to composite materials by Tsai.

Recently, magnesium alloy is in the limelight as ECological material with high ability of recycling and lightweight property.
Especially, because of outstanding properties as a structural material, the magnesium alloy is in great demand.
On the other hand, magnesium alloy is in the limelight as ECological material.
The magnesium alloy has several outstanding characteristics as a constructive material.
Effectiveness of hybrid welding Although the magnesium alloy is remarked as constructive material, any report on YAG laser/ TIG arc hybrid welding of magnesium alloy is not seen.
