AB - As a supplement of current wired gas monitoring system, wireless sensor network can be used to 
cover  the blind  area,  and  to diagnose  the faults  of wired system.  The  concept of novel  chain-type wireless 
sensor network (NCWSN) for gas monitoring in coal mine with multi-sections is defined. The connectivity of 
NCWSN is considered too. To focus on gas monitoring, the advantages of NCWSN for gas monitoring are 
introduced first, then two energy-efficient methods are adopted in gas monitoring NCWSN which are node 
scheduling  and  data  fusion.  The  scheme  of  node  scheduling  can  keep  balance  of  the  energy  cost  by 
transmitting energy distribution frame in certain section. The scheme of data fusion can reduce transmission 
data  bits  by  adopting  fuzzy  sets.  Finally,  performances  of  NCWSN  are  investigated  including  energy 
efficiency and network capability. It is shows that energy efficiency is improved to double by adopting node 
scheduling  and  data  fusion.  In  addition,  it  is  important  to  keep  the  balance  among  energy  cost,  network 
capability and detection precision by choosing appropriate number of sections.
