In the coal major province of Henan, a new round of coal resource integration was launched in March this year. More than 90% of the small coal mines have signed merger and reorganization agreements, and the coal enterprises in the province have achieved phased results.
According to the relevant person in charge of the Henan Provincial Department of Industry and Information Technology, 456 of the 466 small coal mines identified by Henan Province that should be involved in mergers and acquisitions have signed formal agreements for mergers and acquisitions, and 10 small coal mines have automatically withdrawn and For reasons such as property rights disputes, no formal agreement has been signed.
According to the requirements of the Henan Provincial Government for the merger and reorganization of this round of coal enterprises, by the end of this year, Henan will strive to build three large-scale coal enterprises with an annual output of 50 million tons. The coal resources controlled by the backbone coal enterprises account for the province's coal resources. More than 85% of the output accounts for more than 75% of the province's total output, and the production scale of a single mine is not less than 150,000 tons per year. At the same time, the proportion of the equity of the merger and reorganization of the main enterprises in the merger and reorganization of coal mines shall not be less than 51%.
According to reports, at present, the backbone coal enterprises in Henan Province have invested nearly 5 billion yuan for mergers and acquisitions. In order to make the integration truly in place, the relevant functional departments of Henan Province will also improve their management by coordinating the province's colleges and universities to help enterprises cultivate relevant professional talents, promote the training of “five-time†mine managers, and send management teams to small coal mines. Safety level, deep integration.
The soft-type permeable pipe is the supporting pipe body of the anti-rust spring coil, which forms the high compressive soft structure and the non-woven lining filter, so that the sediment impurities can not get into the pipe, thus achieving the effect of net seepage.The overlying layer of polypropylene filament is of excellent absorbent and can quickly collect the excess water in soil.Rubber band makes wall coating layer and the spring steel tube body organic body, has the very good waterproof function in all directions, osmosis water seeping into the pipe, and sediment impurities is blocked outside the pipe, so as to achieve the same permeable, filtration, drainage purposes.
Connection mode:
With convenient and reliable for the principle of construction, Ф 50 mm according to tunnel ring to the length of the permeable tube production and longitudinal Ф permeable tube length 100 mm 6-30 m connection has a direct, tee joint, can be easily connected.
Main advantages:
pore diameter is small, all-round permeable, good permeability;
tensile high crushing strength, long service life;
corrosion and microbial erosion resistance;
continuity on the whole, less joints, cohesion is convenient;
light weight, convenient construction;
texture soft, good combined with soil;
Application scope:
