        針對我國煤礦頂板運動型礦震及誘發災害頻發的現狀,采用現場調查?理論分析?現場監測等方法,對頂板運動型礦震及誘發災害發生機制?預測和工程分類技術進行了研究,得到以下主要結論:① 基于關鍵層運動模式將頂板運動型礦震分為關鍵層斷裂型?關鍵層回轉型和關鍵層滑移型3類礦震,建立了基于“關鍵層運動狀態”的頂板運動型礦震的能量預測模型,分別提出了3類頂板運動型礦震能量的計算方法;② 基于頂板運動型礦震誘發井下和地面災害機制,建立了頂板運動型礦震誘發井下沖擊地壓和地面建筑物震動損害的一體化力學模型和評估方法,為煤礦頂板運動型礦震誘發災害的預測提供了基礎;③ 提出了分類防控?源頭減震?吸能抗震協同防控頂板運動型礦震的理念,形成了以低礦震能量?低圍巖密度和高抗震能力為基礎的煤礦頂板運動型礦震及誘發災害防控體系,開展了地面直井壓裂源頭防控頂板運動型礦震的技術試驗研究;④ 根據工作面在壓裂區開采期間的礦壓顯現和相似材料模擬試驗結果,大范圍壓裂措施能夠降低大能量礦震發生頻次,但也可能改變關鍵層運動模式,甚至增大井下礦壓顯現強度?

      • Abstract

        In view of the current situation of frequent occurrence of roof movement type mine earthquake and disasters induced in coal mines, the occurrence mechanism, prediction and engineering classification technology of roof movement type mine earthquake and disasters induced were studied by means of field investigation, theoretical analysis and field monitoring. The following main conclusions were obtained:① based on the motion mode of key strata, the roof movement type mine earthquakes were divided into three types: key strata fracture type, key strata back transition type and key strata sliding type. The energy prediction model of roof movement type mine earthquake based on the motion state of key strata was established, and the energy calculation methods of three types of roof movement type mine earthquakes were proposed respectively.②Based on the mechanism of underground and ground disasters induced by roof movement type mine earthquake, an integrated mechanical model and evaluation method of underground rockburst and ground building vibration damage were established, which provided a basis for the prediction of coal mining type mine earthquake induced disasters. ③ The concept of collaborative prevention and control on roof movement type mine earthquake using classified prevention and control, source damping, energy absorption and anti seismic was put forward, and the prevention and control system of roof movement type mine earthquake and induced disasters based on low seismic energy, low surrounding rock density and high seismic capacity was formed. The test research on the prevention and control of roof movement type mine earthquake by surface vertical borehole fracturing source was carried out.④ According to the mine pressure behavior during the mining of the working face in the fracturing area and the results of similar material simulation, the large scale fracturing measures can reduce the occurrence frequency of large energy mine earthquakes, but it may also change the movement mode of key strata, and even increase the underground mine pressure behavior intensity.
