Outburst of coal and gas represents a significant risk to the health safety mine personnel working in development longwall production face areas. There have been over 878 outburst events recorded twenty-two Australian underground mines. Most incidents associated with abnormal geological conditions. Details mining experience conditions where content was above current threshold levels are presented discussed. Mining suggests that for below 9.0 m3/t, carbon dioxide (CO2) rich seam does not pose...
Abstract The gas content is crucial for evaluating coal and outburst potential in underground mining. This study focuses on investigating the in-situ seam sorption capacity a representative with multiple sections (A1, A2, A3) Sydney basin, where CO 2 composition exceeds 90%. fast direct desorption method associated devices were described detail employed to measure components ( Q 1 , 3 ) of seam. results show that total T ranges from 9.48 m /t A2 section 14.80 A3 section, surpassing Level...
Desorption rate index (DRI) was presented to the Australian underground coal industry in 1995 as a means for determining outburst threshold limits seams. DRI is measure of gas volume released from sample first 30 s crushing during Q3 stage content testing, multiplied by ratio between measured and QM. Relationships were identified QM both CO2 CH4 rich samples collected Bulli Seam at West Cliff Colliery that relationship referred Benchmark. The mining limit values specified time, when applied...
Australian coal mines currently use gas content to assess outburst risk. The threshold values for each mine are indirectly determined from measurement of volume liberated 150 g samples during Q3 residual testing. It has been more than twenty years since this method, known as desorption rate index (DRI), was presented the industry, and in that time, there have significant changes mining conditions limits used at benchmark Bulli seam mines. NSW Regulations list matters be considered developing...
Australia produces both black and brown coal is the world's fourth largest producer of coal, after China, USA India. Australian underground mines operate under controlled safety codes. The establishment mine management system, including 1994 outburst plan, contributed to a significant improvement in leading non-fatality related incidences since 1994. risk, as part overall health system described. Also discussed are introduction threshold limit values desorption rate index which forms basis...
Abstract During the recent development of Zhao Dong field in Bohai Bay, a One-Trip Multizone Sand Control System was combined with frac pack treatments for efficient completions series stacked pay sands. These technologies were used to complete total 32 zones (28 packs and 4 circulating gravel packs) eleven wells, record time. This paper examines factors that contributed success these operations. The system allowed pumping operations on each well proceed little or no interruption. While...
