| Abstract: | Coal and gas outbursts has become one of the serious mine disasters.At present,method of drill cuttings index is commonly used in the prediction of coal and gas outbursts.And the accuracy of drill cuttings and gas desorption index measurements is most key for the prediction of coal and gas outbursts.In this paper,the process,steps of the prediction as well as the factors influencing the errors of predicting indexes are analyzed,the matters to which attention should be paid in the predicting process and the measures of reducing the errors are put forward also. |

| Keywords: | Coal and gas outbursts Drilling cuttings weight Gas desorption index of drill cuttings Error analysis |
