Mining targets are divided into two general categories of materials: placer deposits, consisting of valuable minerals contained within river gravels, beach sands, and other unconsolidated materials; and lode deposits, where valuable minerals are found in veins, in layers, or in mineral grains generally distributed throughout a mass of actual rock.
using non-combustible, fire-resistant and non-sparking materials to build explosive material storage facilities and installing correct safety devices preventing unauthorised people from getting inside, ensuring that areas surrounding storage facilities for explosive materials are clear of rubbish, bushes, dry grass or trees within a 10-m radius and placing unused explosive materials in a protected location, as soon as practicable after charging is completed, etc.

In this article, the chrome tanned cattle (pig) leather and unsaturated polyester resin or epoxy resin were used as raw materials, leather/resin composite material was prepared.
Before 1970 reports dominantly focused on uses not requiring extensive pretreatment of tanned wastes, including the manufacture insulators, building materials, fibrous sheets, and shoe soles.
It is an effective way for solid leather wastes treatment which combines the leather waste with other materials to form composite materials.

Single phase LiMn0.3Co0.3Ni0.3Ti0.1O2 materials are prepared using a self-propagating combustion method.
The discharge capacities obtained was 143 mAhg-1 in the first cycle for both materials.
The XRD patterns clearly show that the materials are single phase and pure.
The images showed that all the samples are well-formed of polycrystalline materials.

In view of the importance of these materials, many different methods, such as electrospinning[3], nanofiber seeding[4], electrochemical polymerization[5], template synthesis[6] and template-free method which is also called as self-assembly method[7], have been employed to prepare nanostructures of the PANI and substituted PANI.

So the pixels unit representing the same material was adjusted to the same gray value at the same time.
Conclusions In this paper, a reasonable digital modeling method is realized on the basis of real soil fabric and computed back analysis using finite element method is applied to study the thermal conductivity of soil, conclusions are as follows: The typical idealized calculation models of thermal conductivity for porous materials may be not suitable for the precise prediction of the thermal conductivity of soil.
