Kelebihan metode step room and pillar method adalah pengangkutan di dalam permuka kerja hampir tidak memerlukan tenaga penggerak karena dapat berjalan sendiri, misalnya melalui jalan penghubung. Kerugian metode step room and pillar method adalah memerlukannya tenaga kerja yang banyak untuk membawa masuk peralatan, sehingga volume produksi tergantung dari banyaknya alat mekanis yang tersedia.
