济宁二号煤矿153上01工作面为十五采区首采工作面，工作面回采中直接顶垮落步距，老顶初次来压步距无同采区参照，在掌握工作面直接顶、老顶厚度及岩性的条件下，本文主要阐述工作面回采前，利用板模型和梁模型对直接顶垮落步距、老顶初次来压步距进行计算，推算出直接顶、老顶初次步距，有利于在工作面直接顶垮落及老顶初次来压前做好预测预报工作，确保来压期间的安全。
濟寧二號煤礦153上01工作麵為十五採區首採工作麵，工作麵迴採中直接頂垮落步距，老頂初次來壓步距無同採區參照，在掌握工作麵直接頂、老頂厚度及巖性的條件下，本文主要闡述工作麵迴採前，利用闆模型和樑模型對直接頂垮落步距、老頂初次來壓步距進行計算，推算齣直接頂、老頂初次步距，有利于在工作麵直接頂垮落及老頂初次來壓前做好預測預報工作，確保來壓期間的安全。

No. two Jining coal mine 15301 working face fifteen mining area of first mining face, mining face of immediate roof caving step dis-tance, roof first weighting step without the same area reference, immediate roof, in mastering the working face roof thickness and lithology con-ditions, this paper mainly expounds the work face before, on the immediate roof caving step distance, roof first weighting step distance is cal-culated by plate model and beam model, calculated the direct roof, roof first step, is advantageous in the face of immediate roof caving and roof first weighting is done before the forecast work, ensure that the pressure period the safe.
