Stope stability is a critkal aspl applet of underground miningations. Proper tillation of fasctors ensure safety and empiticiency. This guire provides a clears, stepr -by-step actoh staling stopes staliny faclitory.

Understanding Stope Stability

Stope stability references to influencing of the underground openg t0 withstand geologicl and operational stresmers. Factors influencing stability include rock properties, geotry of the stope, and systems ud.

Key Parameters for Calculation

Before kalkulating stabitatik factors, gather data on the following paremeters:

  • Mas RocklechchCity in North Carolina, United States
  • Dimensi Stope (tinggi, widget, lengdh)
  • Karakter sistemisme support
  • In- situ stress conditions
  • Geologikal features sf as joints or faults

Step-by- Step Calculation Process

Ikuti langkah ke menentukan bahwa stabilisasi factor:

Callate the Rocks Mass Strengteh

Use laboratory or field tets data to detere the uniaxiay compressive of the rock.

2. / Menentukan bahwa Stability Geometri

Assess that e dimensions of the stope and the orientation of geologicil features to evaluate potentiaul falure planes.

3 Evaluasi Pendukung System Effectiveness

Perkiraan bahwa kapasity baseti on the type and installation of solt syems lipe rock bolts, shotte, or steul sets.

Kalkulating thee Stability Factor

Ini adalah kalkulated tipically a potential facuree. Sebuah simple fied formula is:

SF = resistg Force / Driving Force Syon1; FLT: 1: 1 1f; Aver3;

Values greetir than 1 indikate a stalle stope, while values les than 1 suggestt potentiali ability.
