The invention relates to the technical field of mining engineering, in particular to a support method for a withdrawing channel. The support method achieves full-negative-pressure ventilation during highly gassy mine fully mechanized coal mining face support withdrawing. After lasting mining of a fully mechanized coal mining face is ended, the self-excavation withdrawing channel is formed through coal cutting of a coal cutter, high-strength anchor rod (cable) support is performed on the withdrawing channel, the roadway retaining mode of driving nogs behind a sheltering frame is omitted, and one-off support is utilized for achieving full-negative-pressure ventilation during support withdrawing. According to the top plate structure of the withdrawing channel, the method of high-pre-stress anchor rod (cable) support is adopted for surrounding rock control. Anchor rods (cables) are adopted for supporting the withdrawing channel in a cantilever mode, nog construction in a traditional support withdrawing mode is basically eliminated, and support strength can meet the requirement for a ventilation section in full-negative-pressure support withdrawing. Through innovating the full-negative-pressure withdrawing channel support mode, the labor intensity is lowered to the maximum degree, the support withdrawing efficiency is improved to the maximum degree, and finally the safe, efficient and economical support withdrawing mode is achieved.

Each rainwater treatment module is composed of a collection device, a rainwater discarding device, a filtering and purifying device and a storage and leakage device which are arranged on the ground or on the lower portion of the kerb, wherein the rainwater discarding device and the filtering and purifying device are arranged on the storage device, the collection device is connected with a water inlet of the rainwater discarding device through a pipeline, the rainwater discarding device is communicated with the filtering and purifying device through a liquid guide opening, and the filtering and purifying device is communicated with the inside of the storage and leakage device through a rainwater collection pipe. According to planned initial rainwater discarding values of cities, the functions of rainwater collection, precise discarding, filtering, storage and leakage can be precisely achieved under any rainfall condition, flood drainage safety can be effectively guaranteed, the structure is reliable, and maintenance is convenient. Meanwhile, rainwater treatment conditions in an implementation area can be monitored as a whole, big data management of sponge city planning is achieved, and the ecological environment in the area is improved.

Method for smelting ash iron by using cupola furnace
The invention discloses a method for smelting ash iron by using a cupola furnace, and belongs to reduction of iron ore and manganese ore. The raw materials comprise the following materials in percentage by mass: 0-70 percent of iron ore powder, 0-60 percent of manganese ore powder, 0-10 percent of silicon carbide, 5-15 percent of reducing agent, 0-10 percent of limestone powder, 5-15 percent of dolomite powder, 1-5 percent of fluorite, 0-5 percent of adhesive, 0-5 percent of water and 0-35 percent of scrap steel. According to the method, a technological line is shortened, so that the aims of reducing transportation steps, saving power, keeping coke energy greater than 35 percent, reducing production cost per tone by over 30 percent and reducing greenhouse gas and pollutant emission by over 30 percent are fulfilled.
