Aiming at shortcomings of space of mine tunnel is linear space,and the existing regular polygon node coverage model will be affected by tunnel width restrictions,which lead to high redundancy of node deployment and expensive cost,present an isosceles triangle node coverage model of wireless sensor networks( WSNs) in mine tunnel.Under one time,two times and three times of coverage,obtain relationship between distance of adjacent nodes and coverage.Experimental results show that node redundancy of square and hexagon coverage model is 77.78 %,89.7 % respectively,and isosceles triangle three times coverage model is 40.03 %.Isosceles triangle node coverage model decreases coverage redundancy and is more suitable for mine tunnel.
