基于GIS的岩浆侵入对煤层影响的综合评价

Comprehensive Evaluation on Magmatic Intrusion based on GIS Induced in Coal Seam

岩浆侵入可以破坏煤层连续性和完整性,造成煤质变差,煤炭工业价值降低。卧龙湖煤矿10煤层受岩浆侵入影响严重,为了指导矿区更加科学安全生产,实现最大限度地煤炭资源回收,本文利用GIS的空间分析功能,选取挥发份含量,发热量等指标为影响评价基础因子,对卧龙湖煤矿10煤层岩浆侵入造成的影响进行了综合评价分区。分析结果与煤矿开采过程中反馈的资料有良好的对应关系。

The magmatic intrusion distructs coal bed continuity and integrity, makes the coal quality poorer and lowers down coal＇s industrial value. The 10 coal bed of Wolonghu Coal Mine was seriously influenced by magmatic intrusion. For instrucing mining production process to be more scientific and safe, and realizing maximum exploitation on the coal resource, this article selected the volatility and calorific capacity for the influence appraisal foundation factors and made a synthetic evaluation on the influence caused by the 10 coal bed magmatic intrusion of Wolonghu Coal Mine with GIS spatial analysis function. The analysis result had a good corresponding relationship with the data feeded back from recent coal mining process.
