Sparse crowd sensing method for methane concentration field in coal mine fully mechanized mining face

Meikuang Anquan
In view of the lack of methane monitoring points in coal mine fully mechanized mining face, it is difficult to achieve for high coverage methane concentration monitoring in the mining face area. We propose a methane concentration field sensing method in the mining face based on sparse crowd sensing.
