特厚煤层下分层综放开采灾害预防措施
|
摘要
活鸡兔井存在发生顶板灾害、水灾和采空区自然发火灾害的安全隐患,为保证安全生产,需进行有针对性地预防。在对综放工作面开采条件及工况进行分析的基础上,开展了可能发生的灾害辨识;针对顶板灾害预防技术,提出工作面必须沿底板回采等7项不同情形的应对措施;针对水灾预防技术,提出5项应对措施及注意事项;对于采空区自然发火预防技术,提出加强工作面地表巡查与回填等10项措施。采取了针对性的灾害预防技术后,有效预防了灾害的发生,保证了下分层综放工作面的安全回采。
There are safety hazards of roof disasters,water disasters and spontaneous combustion disasters in Huojitu Mine.Based on the analysis of the mining conditions and geological conditions of fully mechanized caving face,the identification of potential disasters was carried out,seven countermeasures for roof disaster prevention,five for flood prevention and ten for goaf spontaneous combustion prevention were put forward.After adopting targeted disaster prevention technologies,the disaster was effectively prevented,and the safe mining of the lower slice fully mechanized caving face was ensured.
