This brief deals primarily with heat storage systems or thermal energy storage, a technology that stocks thermal energy by heating or cooling a storage medium, so that the stored energy can be used later, either for heating and cooling applications or for power generation.Thermal energy storage systems can store heat or cold to be used later, at different conditions such as temperature, place, or power.

According to the technical personnel, in the existing mine mining technology, the roadway excavation is only relying on the boring machine to dig the machine or drill the drilling and digging operation. However, in some mine roadway excavation operations, due to the complex geological conditions, geological structures that are mixed with semi-coal rock and whole rock face are often encountered, and the cross section of the roadway is limited, which can not meet the requirements of rapid exchange between the two machines of the roadheader and the drilling vehicle. , And frequent replacement of excavating equipment will affect coal production and reduce production efficiency. In order to make up for these deficiencies, the Shimeiji Technology Research Group has relied on the technological advantages of the company for many years to develop roadheaders and tunneling rigs, and has boldly carried out independent innovations. Through scientific and rational design methods, it has been able to increase drilling boring operations on the roadheader. Drill arm, research into a unique multi-functional roadheader.
The boring machine can decide whether to use machine digging or drilling and blasting according to rock hardness. When the roadway condition is that the hardness of the whole rock or semi-coal rock is high, the excavation work is stopped first, and the rock drilling system is operated so that the hydraulic rock driller starts the rock drilling operation. When the roadway is semi-coal rock or the hardness is low, no hole operation is required. The drill arm can be retracted and fixed to continue the machine digging operation. During the tunnel excavation in coal mines, it reduced the requirements for the use of space, expanded the scope of application of the roadway, and provided a safe and highly efficient new type of coal machinery equipment for tunneling operations in coal mines. It was also the first in the domestic roadheader products.
Recently, the first multifunctional roadheader independently developed by Hebei Suizhong Energy Shijiazhuang Coal Mining Machinery Co., Ltd. was granted a utility model patent by the State Patent Office. The roadheader can be used for one machine and two uses. It has the functions of machine digging and drilling hole drilling in the process of roadway excavation, and can realize rapid interchange of two functions, effectively reducing the labor intensity of underground workers and improving the speed of roadway excavation. And work efficiency.
