From bottom to top, the three-layer sponge ecological structure comprises a water-resisting layer, a water-containing layer and a topsoil ecological layer. A thickness of the water-resisting layer is 100˜200 cm, a permeability coefficient of the water-resisting layer is 0.35˜0.7 m/d, and a degree of compaction is 1200˜1400 KPa. A thickness of the water-containing layer is 150˜250 cm, a permeability coefficient of the water-containing layer is 10˜20 m/d, and a degree of compaction is 800˜900 KPa. A thickness of the topsoil ecological layer is 40˜60 cm. Soil layer thicknesses and water content may be monitored through a ground penetrating radar.

摘要： The present disclosure provides a noble metal-transition metal-based nano-catalyst thin film and a preparation method thereof, belonging to the fields of energy development and pollutant emission reduction. Based on a micro-nano processing technology, a noble metal-transition metal-based nano-catalyst thin film is loaded on a semi-cylindrical pipe with an inner thread structure, and heat generated is quickly accumulated on an upper surface of the catalyst to establish a large temperature gradient. By the insulation and high roughness of an alumina carrier layer and the inner thread structure of the pipe, a catalyst loading area is maximized and dispersion of noble metal atoms is enhanced. A transition metal-transition metal oxide thin film protects a noble metal nano-catalyst by core-shell wrapping, and a transition metal oxide prevents catalyst deactivation caused by oxygen occupying too many metal active sites.

摘要： The present disclosure discloses an intelligent position sensing system based on spatial three-dimensional model image matching, which realizes three-dimensional precise positioning and target orientation positioning of closed spaces, such as a coal mine. The position sensing system includes a three-dimensional GIS server, a position matching server, a wireless camera, and a wireless access device. Position sensing is realized by comparing an image collected by the wireless camera with a two-dimensional image generated by rendering. The disclosure positions a target without carrying a special wireless positioning card, and can realize three-dimensional precise positioning, including target orientation, by only carrying a camera with a wireless communication function in combination with a wireless positioning technology, a three-dimensional GIS technology, and a digital image processing technology, which can be widely applied to the field of precise positioning of confined spaces, such as factories, coal mines, and subways, and can be widely applied and promoted.

摘要： An automatic coal mining machine and a fluidized coal mining method are provided. A first excavation cabin is configured to cut coal seam to obtain raw coal and to be transported to a first coal preparation cabin for separating coal blocks from gangue. Then, the obtained coal blocks are transported to a first fluidized conversion reaction cabin. The first fluidized conversion reaction cabin converts the energy form of the coal block into liquid, gas or electric energy, which is transported to a first energy storage cabin for storing. Coal mining and conversion are carried out in underground coal mines, so it is not necessary to raise coal blocks to the ground for washing and conversion, thereby reducing the transportation cost of coal, improving the utilization degree of coal, and avoiding the pollution of the ground environment caused by waste in the mining and conversion process.
