In this paper, it first through statistics finds thatthe proportion of gas explosion’s death toll is the largest in the total death toll of Chinse coal mine accidents, andlive-line work is the unsafe behavior causing the most death toll in Chinese coal mine gas explosion accidents. Thenit gives a brief introduction and comparative analysis on the main behavior control methods at home and abroad –American DuPont company’s STOP method, Japanese KYT method of Sumitomo Corporation, and domestic fine,hand pointing and oral description, safety education and training method, etc., and finds that each method has its ownmerits and faults.

On this basis, combining the application of situation teaching and virtual reality in coal mines, twoother unsafe behavior correction methods are proposed for Chinese coal mines: scenario design and virtual realitygames. At the same time, it also suggests that we can first consider and choose live-line work - the unsafe behaviorcausing the most death toll in Chinese coal mine’s primary accident of gas explosion, to design these two kinds ofmethods. 2011 Published by Elsevier Ltd.

IntroductionCurrently Chinese coal mine safety situation shows overall stable and better trend, however, alongwith the achievements, Chinese coal mine safety situation is still very serious compared to othercountries[1]. And unsafe behavior is especially the main reason causing Chinese coal mine accidents.According to the statistics of State Administration of Coal Mine Safety, 70% 80% of Chinese coal mine* Corresponding author.

Reference [3]through overall statistics on the direct reasons for Chinese coal mine major accidents occurring during1980-2000, finds that the human error proportion is up to 97.67% actually. Paper [4] also summarizes thedirect reasons for Chinese coal mine major gas accidents during 1998 2008, and the results clearly showthat the human error proportion is up to 96.86%. Therefore, controlling person’s unsafe behavior in coalmine enterprises is a key measure to eradicate and reduce accidents.2. The specfic statistics on unsafe behaviors of coal mine major accidents2.1. The statistics on Chinese coal mine accidentsThe casualty accidents in coal mine industry generally have the following eight categories: roofaccidents; gas accidents; mechanical and electrical accidents; transportation accidents; blasting accidents;fire; water damage accidents; other accidents, in which the gas, roof and blasting accidents are one of thechief criminals causing major accidents. The authors in the accident inquiry system of StateAdministration of work safety government website, have inquired coal mine accidents with each deathtoll over 1 person, total accident number 2279 and total death toll 8079 persons during 2004/11-2009/11,and the statistics results with death toll from more to less are shown in Table 1. From Table 1, it can beseen that the proportion of gas explosion’s death toll is the largest in the total death toll of Chinse coalmine accidents.Table 1.

Unsafe behavior statistics on coal mine gas explosionIn order to find the unsafe behaviors causing the highest coal mine death toll accident of gas explosion,the authors have investigated gas explosion accidents with total accident number 433 and total death toll10056 persons during 1950-2006. Here, the gas explosion accident cases in 1950-2000 are from《Chinese coal mine accidents and expert comments》(the first volume) with authors WANG Jie-fan, LI
