Study on the process synergic mechanism of whole life cycle of under-well project in coal mine

According to the principle and method of synergetics and project life cycle,and aiming at the current situation of synergy lack of under-well project of coal mine,firstly,the phases and processes of under-well project life cycle of coal mine were recognized; secondly,three synergic systems of whole life cycle of under-well project were established,including single project,one working surface projects and several working surface projects; then,the content of the three synergic systems was summarized; finally,the formulas of order parameters of the three synergic systems were listed. It has important theoretical and practical significance for systematically improving the existing management mode of coal mine production,the synergy of the whole life cycle of under-well project of coal mine,and economic benefit and labor efficiency of coal mine.
