Henan's new energy achievements reached the international advanced level

On November 4th, the reporter learned from Henan Energy Chemical Group that the group's Xinjiang company’s “Cizi Mining Mining Technology and Application of Close-range Coal Seam Hard Roofing” has recently passed an expert review organized by the China Coal Industry Association. The project has reached the international advanced level.

It is understood that through the technical breakthrough, Henan Energy Chemical Group Xinjiang Company has overcome three difficulties, namely, the biggest danger source for the “hanging structure” above the cut-off boundary of the goaf, and strengthened the safety management in the transition phase of mining; Faced with the difficulties encountered by multiple mining operations at the same time, the mining laneway adopts the “small pillar-protected lane-outside layout” approach; on the basis of the micro-earthquake monitoring and early warning indicators, a suitability for multiple mining impacts is formed. Under the ascending mining face security technology system. In actual production, the recoverable reserves of the upstream mining face of the Kuchas Mining Industry are 1.89 million tons. Through the implementation of this innovative project, the operating income is increased by 340 million yuan, the profit is 153 million yuan, and the service life of Kuchai Well is extended by 2.1 years. Safe and efficient mining.
