On the basis, such technological approaches were brought forward to ensure support effect in the soft rock roadways by improving the materials and formulations of the resin capsules and increasing the support density and the anchorage length appropriately.
Firstly, the materials and formulations of the resin capsules should be improved for developing a new kind of resin capsule which was suitable for bolt support in the soft rocks.

Therefore, it is greatly urgent to develop high-performance advanced electrode materials to be used in alkaline secondary batteries.
Cobalt or cobalt-based alloys were developed and used as anode materials in alkaline secondary batteries.
The researchers have been trying to find Co-B alloys with better cycle stability, higher electrochemical capacity, and higher rate discharge-ability used as negative electrode materials for alkaline secondary batteries based on the optimization of preparation methods [11,12], the select of raw materials [3], the control of the synthesizing conditions [13] and multi-component alloying [8,14,15,16].

The characteristic of the new process is by using of the cheaper molybdenum oxides powder as alloy agent which can improve the flexibility of choosing main raw materials.
In the present study, molybdenum oxides was used to smelt H13 die steel, and molybdenum oxides usually as raw materials to producing ferromolybdenum.
Raw materials were placed in the bottom of EAF, such as molybdenum oxides, reducing agents, steel scrap.
