【摘要】：為研究復雜空區(qū)下開采區(qū)域煤自燃探測治理及和整體防控,論文首先通過理論分析了煤自燃的誘發(fā)機理、發(fā)生發(fā)展過程及內(nèi)外在影響因素,并結(jié)合復雜空區(qū)下開采的特殊環(huán)境分析了空區(qū)下開采的煤自燃特點及發(fā)火可能性大的高位區(qū)域,然后以北祖礦為例進行研究。采用小型煤自燃程序升溫實驗方法對北祖礦4#、9#煤層的煤樣進行試驗,得出了通入空氣條件下低溫階段隨煤體溫度升高煤樣釋放出的氣體組分和濃度,得出適用于該礦的指標氣體,并結(jié)合煤自燃階段躍遷理論建立了基于指標氣體的煤自燃預警體系。根據(jù)北祖礦的現(xiàn)場條件,采用示蹤氣體法對9209巷漏風匯進行了測定,根據(jù)巷道內(nèi)指標氣體定點采樣的結(jié)果對老巷自燃狀況進行預警,應用紅外熱像儀對巷道表面溫度監(jiān)測,進而采用漏風段巷道表面噴漿和區(qū)域均壓、老巷注漿堵漏等技術(shù)方法。采用FLACE3D數(shù)值模擬方法對開采中保護煤柱的損傷狀態(tài)進行模擬,而后在此基礎(chǔ)上提出工作面自燃監(jiān)測和預報設(shè)計、煤自燃預防開拓布局、自動控制正壓通風防治采煤工作面CO氣體等一整套工作面煤自燃防控方案。論文研究成果可以為類似復雜空區(qū)下開采條件的煤自燃防控、探測和治理提供理論和技術(shù)支撐。
[Abstract]:In order to study the detection and control of coal spontaneous combustion in the mining area under complex empty area, the paper firstly analyzes the inducing mechanism, the process of occurrence and development and the influencing factors inside and outside of the coal spontaneous combustion through the theoretical analysis. Combined with the special environment of mining under the complex goaf, the characteristics of spontaneous combustion of coal and the high position area where the possibility of combustion is high are analyzed, and then the study is carried out in the north of Zu Mine as an example. By using the method of small coal spontaneous combustion programmed temperature test, the coal samples of 4 #yun9# coal seam in Beizu Coal Mine were tested, and the gas components and concentrations released by coal samples at low temperature stage under the condition of air entry were obtained with the increase of coal body temperature. The index gas suitable for the mine and the coal spontaneous combustion early warning system based on the index gas are established in combination with the coal spontaneous combustion stage transition theory. According to the field conditions of Beizu Mine, the air leakage sink of 9209 roadway was measured by the tracer gas method, the spontaneous combustion condition of the old roadway was forewarned according to the result of the fixed point sampling of the index gas in the roadway, and the surface temperature of the roadway was monitored by the infrared thermal imager. Then, the air leakage section surface grouting and regional pressure, the old roadway grouting plugging and other technical methods are adopted. FLACE3D numerical simulation method is used to simulate the damage state of coal pillar protection in mining. Based on this, the monitoring and prediction design of spontaneous combustion in coal face and the development layout of coal spontaneous combustion prevention are put forward. Automatic control of positive pressure ventilation to prevent and control coal spontaneous combustion in mining face, such as CO gas. The research results of this paper can provide theoretical and technical support for coal spontaneous combustion prevention, detection and treatment under similar mining conditions in complex empty areas.
